Central Europe 2017

November 3rd - 5th

Hotel Ossa Congress & Spa

Rawa Mazowiecka, Poland

About the conference

phpCE is a first edition of a community conference for PHP programmers and enthusiasts. The meeting was stablished by merging two nation-wide events: PHPCon Poland and Brno PHP Conference.

An undoubted success of the PHPCon Poland, grown within seven years into one of largest PHP community conferences in Europe disposed us to take it a step further and organise yet bigger event, reaching out to expectations of potential attendees from Central Europe as well as people just beginning their PHP career. All the more we are proud to welcome our colleagues from Brno PHP Conference team and hope to efficient cooperation.

The phpCE cycle starts in Poland and the Ossa Congress & Spa hotel, well-known to PHPCon Poland attendees. The plan is that the conference will regularly move from one country to another and next edition (2018) should fire-up in Czech Republic. It is completely no barrier to do it Germany, Hungary, Austria, Slovakia or the Baltic states. Dozens and dozens depends on local PHP groups engagement, so, if you feel that phpCE Conference should host in your country, don't wait and contact us – we are really ready to do it!

Why you should join us?

Huge event

You attend in the biggest PHP conference in this part of Europe: over thousand people working and thinking just like you, in the same venue.

Diversified difficulty levels

Feel free to choose among the Relaxing, Intermediate and Geek paths.

Workshop Friday

We start from workshop day. It's a practical knowledge for the asking and great opportunity to clarify all details!

Possibility of overnight stay on site

Choose your favourite accommodation site! However Ossa hotel offers a large amount of hotel rooms, you can still stay outside and buy the phpCE ticket, including board only.

Contests and rewards

Our sponsors are happy to organise different kinds of contests with many valued rewards. It's worth to visit us and take part in it!

Entertainment zone

Our sponsor room is a kind of neverending chillout zone. Moreover, we have something for your ear and soul: a positive and irrepressible celtic music of the Carrantuohill group on the Saturday's night.


Ossa Congress & Spa**** hotel

We will third time stay (including PHPCon Poland) in fifth largest hotel in Poland, the Ossa Cogress & Spa. It is situated in calm countryside, away from city noise, which gives a possibility to take part both in conference and active outdoor rest.

Hotel is located in the small village with same name, between Rawa Mazowiecka and Biała Rawska, near the S-8 motorway and about 60 kilometers from the Warsaw Chopin (WAW) airport. Initially, hotel makes available the amphitheatre hall, congress hall, workshop room and bedrooms in four-star standard and diversified comfort level (Standard, Premium, Standard Suite, Premium Suite) to beglad even most particular guest tastes. The slanted lecture hall, unique among Polish hotels and exceptionally spacious, also waits for you.


aircraft, then shuttle or cab

Best airport for landing is the Warsaw Chopin Airport (WAW). There'll be a shuttle-bus or cab you can take to get to the hotel and return. In order to book it, send us an e-mail before you buy a conference ticket. The cost of it is 10 € in one direction or 20 € in both.

Bus or cab driver will wait at agreed time in the airport departures hall. You can recognise him by the "phpCE Conference - Ossa" plate.

public transport

There are quite a bit buses to Rawa Mazowiecka departing next to the Warsaw West railway station.
When you reach Rawa Mazowiecka, change bus to Biała Rawska (via Lesiew, not via Babsk) or evt. Grójec. The important is that bus should stop in Wólka Lesiewska, because it's your final stop there.
Next, walk along a secondary road with direction Biała Rawska. Turn left on the first crossroad towards the Ossa (you can find an advertising board of the Ossa Congress & Spa hotel there). After a few hundred meters you'll see the hotel by left hand.
Bus timetable from Rawa Mazowiecka you can find at this website.


The best way to get to Ossa is Warsaw – Wrocław S-8 motorway. Rawa Mazowiecka is situated between Warsaw and Piotrków Trybunalski (A-1 highway junction). You must leave S-8 motorway on the "Rawa Mazowiecka" junction, but not on "Rawa Mazowiecka Południe (south)". Then choose the 925 secondary road to Biała Rawska. After about 9 kilometers and the Wólka Lesiewska village turn left to Ossa. There's an advertising board of the Ossa Congress & Spa hotel. After a few hundred meters you'll see the hotel at your left.

Jak TDD pomaga w pisaniu wartościowych testów jednostkowych?
Michal Kopacz, Łukasz Wróbel 4h

W swojej przygodzie z pisaniem testów jednostkowych zapewne zdarzyło Ci się że:
- sporo czasu zajęło Ci przeczytanie i zrozumienie co robią testy,
- zmieniłeś kod pod kątem nowych wymagań i spowodowało to, że musiałeś wprowadzić sporo zmian w testach,
- zaimplementowałeś funkcjonalność i pozostało Ci tylko napisać testy, ale nie było prosto je napisać więc w końcu zrezygnowałeś,
- zaimplementowałeś funkcjonalność, ale już nie miałeś czasu aby dopisać testy.

Takie sytuacje mogą powodować, że nie widzisz wartości w pisaniu testów jednostkowych, bo ich koszt przewyższa zyski jakie dają. Na warsztatach dowiesz się i przećwiczysz, jak można minimalizować koszt tworzenia i utrzymywania testów jednostkowych używając Test Driven Development.

W kilku iteracjach TDD przećwiczymy:
- przekładanie wymagań na testy jednostkowe,
- poprawianie czytelności testów jednostkowych,
- stosowanie fazy refaktoryzacji.

- własny laptop,
- zainstalowane: PHP 7.1, Git z kontem na Githubie, Composer, dowolne środowisko IDE, PHPUnit 6.4 (lub inne narzędzie do testowania jednostkowego, którego używasz)
- podstawowa umiejętność w dziedzinie pisania testów jednostkowych (asercje, mocki).

Functional testing made easy with PHPUnit & Selenium
Ondrej Machulda 4h

Learn how to use PHPUnit to test your app in a real browser using Selenium. This hands-on training will show you how to start writing & executing functional (aka end-to-end) tests with Selenium in a minute.

If you already use PHPUnit for your unit tests, there is no need to switch to a different tool or platform just to write functional tests. You can keep productivity from using your familiar environment of PHPUnit and just add some additional integration with Selenium.

So we will take advantage of PHPUnit and php-webdriver integration with Steward library, and use Docker to run Selenium without any other dependencies.

The training will cover:

- setting up local development environment (using Docker)
- practical examples of functional tests implementation
- exploring possibilities of Selenium WebDriver
- parallel test execution using Steward
- hands-on Page Object design pattern
- dealing with asynchronous elements of web-pages (AJAX, JavaScript)
- general tips & tricks how to keep a maintainable suite of functional tests in a long-term.

- own laptop,
- Docker up & running
- VNC client (eg. vncviewer or Remmina on Linux, on Mac OS the builtin client)
- locally installed PHP 5.6 / 7.0 / 7.1 for command line (no need of apache etc.)
- locally installed composer
- locally installed Git
- IDE (like PhpStorm) will help you a lot

Let your tests drive your development
Michelangelo van Dam 4h

Test driven development (TDD) is still a subject all developers agree upon it's a great thing, but never get around to actually do it for many reasons. In this workshop I use real world business requirements on legacy code for which we need to fix bugs and add features, but we're doing it in a TDD way.

No matter if you're already a testing veteran or a junior developer just started working yesterday, this workshop will give you the skills and passion to continue your career as a Test Driven Developer.

Other Info:

This workshop requires attendees to run PHP 7 on their laptops or have a VM running with PHP 7 enabled on it. I will provide the full packages on a thumb-drive that will be used during the workshop.

This workshop contains a small sections for developers new to PHPUnit, but the examples and exercises are aimed at those developers that are already familiar with PHPUnit and have an advanced knowledge of PHP. The exercises require knowledge of GIT branching and the correct usage of composer.

Requirements for participants:
- PHPUnit 6.1 or higher
- PHP 7.1 or higher (optionally XDebug enabled)
- GIT 2.10 or higher

Symfony 4 - Hands On Tutorial (part 1)
Hugo Hamon 4h

Symfony 4.0 will be released at the end of November 2017 and will change the way you develop Web applications with Symfony. In this workshop, you'll discover the new recommended best practices promoted by the Symfony Core Team. You'll learn how to install third party packages with Symfony Flex, configure your application with environment variables or leverage the new dependency injection container features, use the new PHP 7 features, and much more! This two part workshop is a practical training where you'll learn how to build a small full featured web application with PHP 7 and Symfony 4.0.

BDD with hexagonal architecture
Tomasz Kunicki 4h

The aim of workshop is to create a testable structure using the concept of Hexagonal architecture with Behavioral Driven Development by Behat v3.3 and configuration functional tests with container. We will focus on setting up a basic structure and configuring the test framework. We'll talk about the pros and cons of this solution. Using that example, we'll show BDD in practice. After the workshop, participants should be able to understand the concept of BDD and could create a basic structure integrated with Behat. This project should be testable on functional level tests. Additionally, the participant will understand the pros and cons of this approach in project.

- own laptop,
- PHP7.0,
- Git.

Symfony meets Elasticsearch
Michal Kómoch, Michał Jankowski, Bartosz Telesiński 4h

To szkolenie ma na celu przedstawienie prawidłowej integracji i użycia biblioteki FOSElasticaBundle w połączeniu z Symfony3. W trakcie warsztatów postawione zostanie pełne środowisko w kontenerach docker oraz zaprezentowane zostaną przykłady użycia ręcznego tworzenia zapytań do Elasticsearch, a także sposób ich reprezentacji za pomocą Query Buildera w frameworku Symfony3.
Po zakończeniu szkolenia każdy z uczestników będzie posiadał solidną wiedzę na temat konfiguracji i wykorzystania Elasticsearcha w połączeniu z Symfony.

- Zainstalowany GIT i umiejętność korzystania z jego podstawowych komend
- Ulubiony edytor kodu

Demonstrating advanced layouts and block management in Symfony based web solutions
Ivo Lukač 4h

Handling layouts and blocks in templates does the job but it is very rigid, not flexible and hard to maintain. It gets even more complicated with responsive or adaptive rendering for different screen sizes.
To improve this we built a tool based on Symfony full stack so that we can:
- easily manage different layouts with zones
- add/more/remove blocks to zones with a drag and drop interface,
- reuse blocks with shared zones
- implement custom blocks by simple template and/or controller override,
- apply layouts to routes with conditions like user roles, geolocation, time, languages, etc.
The tool is envisioned to be used in front of a backend system like a CMS or a eCommerce and provide a faster and more agile way to develop complex web solutions.
This tutorial will not be hands-on so participants don't need to have anything installed. Bring your own laptop only.

Symfony 4 - Hands On Tutorial (part 2)
Hugo Hamon 4h

Optional lunch
Registration & check-in
Official opening
Keynote: How to get the most out of a tech conference!
Andreas Heigl 30m

What are the DO's and DONT's for conference-attendees. How to make the most out of the conference-ticket we posses. I will share some tips from my past conference experiences on how to get the most out of a tech conference.

Jak zacząć, aby nie żałować?
Piotr Horzycki 1h

PHP stanowi bardzo elastyczne środowisko, które można wykorzystać zarówno do małych studenckich projektów, jak i dużych, komercyjnych serwisów internetowych. Nie narzuca przy tym jednolitej architektury systemu - to my musimy o nią zadbać. Co zrobić, gdy mamy przed sobą pusty projekt (greenfield)? Jak dobrać właściwe narzędzia, by później nie żałować wyboru? Jak przygotować się na nieoczekiwany wzrost złożoności projektu?

Opowiem o burzliwej historii PHP, pierwszym PHP-owym szale w Polsce z lat 2000-2005, pojawieniu się frameworków MVC i ORM, które automatyzują stawianie projektu - i dlaczego nie zawsze można im ufać. Opiszę podstawowe narzędzia, z którymi pracuję dzisiaj: Vagrant, Composer, PHPUnit, Phing, PHP Code Sniffer. Co warto od razu zapiąć w greenfieldzie, aby dalsza praca była przyjemna i efektywna? Jaką architekturę wybrać? Jak pogłębiać swoją znajomość PHP? Jakie są najnowsze trendy w tym środowisku?

Żegnaj REST, Witaj GRPC
Pawel Rekowski 1h

Przyzwyczailiśmy się już do komunikacji po REST’cie. Wysyłamy po HTTP requesty w te i z powrotem mając nadzieje, że kontrakt API się nie zmienił. Co by jednak było, gdyby zamiast długich i ciężkich JSONów czy XMLi, mogli byśmy komunikować się w sposób binarny? Co by było, gdybyśmy mieli pewność, że kontrakt w API nie może zostać zmieniony i co by było, gdybyśmy mogli odizolować warstwę komunikacji od serwisu niezależnie od używanego języka? Przyjrzymy się bliżej technologii od Google, czyli Protobuff razem z frameworkiem GRPC.

Z tej prezentacji dowiesz się:
- Czym jest Protobuff oraz GRPC?
- Jaka jest różnica między komunikacją po REST’cie, a po ProtoBuffie
- Dlaczego warto przyjrzeć się tej technologii?
- Jak wyglądało wdrożenie GRPC w BlaBlaCar?
- Jak możesz wykorzystać komunikację binarną w swoim projekcie?
- Jakie są plusy i minusy takiego rozwiązania?

Who's the king; who's the ruler. How to answer the question before it was posted.
Hubert Bryłkowski 1h

I will share with you a story about hashes, what they're good at and what they're bad at. Most importantly how to use them in a not-so-typical way.

I was faced with a challenge to search a database of questions (about 2 million records) and find duplicates among them.
It may look like a pretty simple problem, but doing this efficiently was not trivial. I will explain the algorithms used, discuss their benefits, and show you how I tweaked them to our needs.
My main topic will be MinHash and LSH, with a little reminder about general hashing algorithms.

Bezpieczeństwo aplikacji internetowych
Pawel Makowski 1h

W trakcie prelekcji zostaną omówione najważniejsze kwestie związane z tworzeniem bezpiecznych aplikacji internetowych.
Uczestnik zdobędzie wiedzę na temat OWASP top 10, ASVS oraz podstawowych narzędzi do testowania aplikacji.
Zaprezentuję podatności, tak te popularne o których często się słyszy jak i nieco bardziej ciekawe.

Encryption, authentication and data integrity in PHP 7
Enrico Zimuel 1h

In this talk, we will show how to encrypt and authenticate sensitive data using PHP 7. We will show how to use the new Authenticated Encryption available with PHP 7.1 using OpenSSL. Moreover, we will introduce the usage of the new Sodium functions of PHP 7.2.

Eventual Consistency - Desining Fail Proof Systems
Grzegorz Skorupa 1h

Each day our systems deal with more data, more traffic and more complex tasks. Every large-scale system has to integrate with other internal or external systems. At the same time it should provide up to date information. On the other hand business states high availability and reliability requirements. Those two make designing of such systems difficult. In particular it is difficult to keep your data consistent.

It often happens that not all requirements can be technically met. Fortunately there are theoretical proofs that define what can and cannot be met in what circumstances. During the talk I will present some of the data consistency related problems typical to high traffic systems and try to sketch possible solutions. During the talk I will mention a few words about: CAP theorem, Eventual Consistency, At Least-Once Delivery and Self-Healing Systems.

A hands on introduction to Laravel
Freek Van der Herten 1h

Laravel is an amazing framework that allows you to rapidly create quality applications. If you've never worked with Laravel before, and are interested to know what the fuzz is all about, this is the talk for you.

In this beginner level talk you'll learn how Laravel makes your job easy. We'll go over the stuff that makes Laravel shine like it's expressive routing system, the easy to learn Eloquent ORM, the powerful command line tools, the scheduler, the built-in testing facilities and much more.

Behat - Zaimplementowałeś kilka scenariuszy, Co dalej?
Grzegorz Skorupa 1h

Słyszałeś już co nieco o Behavior-driven development. Nawet samodzielnie napisałeś pierwsze 5 Scenariuszy i zaimplementowałeś je z pomocą Behata. Chcesz podążać tą ścieżką ale twoja głowa jest wypełniona pytaniami i wątpliwościami. Byłem w tej sytuacji 2 lata temu i chcę ci pomóc.

W sieci znajdziesz wiele kursów Behata ale niewiele z nich daje wskazówki jak implemnetować testy w długoterminowym projekcie o dużym stopniu złożoności. Prawidłowe rozplanowanie scenariuszy i ich implementacji, gwarantujące, że nie zmienią się w trudny w utrzymaniu kod, jest trudne. Wytyczne jak to zrobić nie są łatwe do znalezienia w sieci.

Spotkanie rozpocznę krótkim wprowadzeniem do BDD. Następnie przedstawię prosty projekt korzystający z Behata, który będzie prawdopodobnie podobny do twojego pierwszego scenariusza, który napisałeś po przejsciu kursu Behata. W tym momencie zacznę rozszerzać i refaktorować kod tak aby ostatecznie uzyskać skomplikowany framework testujący twoją aplikację. Przedstawię przykładowe rozstawienie testów Behata, które wspiera testy integracyjne, API oraz interfejsu. Postaram się również wyjaśnić jak planować kroki, cechy (features) i konteksty Behata w celu uzyskania kodu łatwego w utrzymaniu i rozszerzaniu.

Domain-Specific Assertions
Sebastian Bergmann 1h

A common language, understood by technical and non-technical stakeholders alike, is essential for good communication in a software project. Combining ideas from Domain-Driven Design and Test-Driven Development, this ubiquitous language can be represented in both production code and test code.

Attendees of this session will learn how to create tests that are easy to write fast to execute, and deliver highly reliable results. They will gain expertise in the confident and effective implementation of automated tests for their software and learn how to implement custom assertions for PHPUnit to represent the common language of their project in test code.

Agile 101
Bartosz Boguszewski 1h

Most of the people when hear Agile think Scrum as this is one of the most popular buzz word. But Agile is much more then Scrum. There are variety of methodologies and frameworks. During this meeting, we are going to talk about origins of Agile. We are going to get familiar with number of methodologies and frameworks like Scrum, Lean, XP, FDD Crystal, DSDM and Kanban. We are going to talk about pros and cons of each of them. Let's see what is out there and decide which one is best for your project and your team.

The GDPR is coming, are you ready?
Michelangelo van Dam 1h

On May 25, 2018 all companies collecting and processing data of people from within the European Union must comply to the General Data Protection Regulation or GDPR. In this talk I'll cover what the GDPR is and how it will impact businesses within the EU and abroad, what can be done to comply to this regulation and how to proceed further.

This talk will not provide you legal answers, but will give you technology solutions that will make your applications compliant to these regulations. Even if you're not processing data from the EU, these solutions will offer you better protection to the data you currently keep and will ensure that in the case of a breach, the impact will be minimum.

Design Principles for MVP
Junaid Masoodi 30m

User experience is the solution for engaging client or user on a site or App. How to design a user experience for MVP (Minimum Viable Product) is very important and how to design right user experience is more important. So how do you ensure that you build the best product when everyone has the same million ideas. We will be talking about MVP and Design principles:

* What is Minimum Viable Product and UI/UX:
* Why MVP?
* The MVP is not about the Product but The product itself.
* UI is not UX and UX is UI.

*Design Principles:
* Unity/HarmonyHierarchy.
* Scale/Proposition.
* Balance.
* Dominance/Emphasis.
* Similarity/Contrast.

* Designing User Experience for Minimum Viable Product
* How MVP and Design Principles should go parallel from day one.
* How to featurise UX for MVP.
* Why touring is important for MVP

By the end of session you will be able to:
* Start working on a product with MVP practices.
* How to design MVP using design principles.
* For the web, how colours, position and placement of blocks affect site traffic.
* How is UI different from UX.
* Why touring is important.

Kompleksowe wprowadzenie do Value Object
Mikolaj Adamczyk 1h

Słyszałeś już o Domain Driven Design i chciałbyś wypróbować to podejście w swoim projekcie? Dobrym sposobem jest rozpoczęcie od wdrożenia w nim kilku Value Object. Pokażę, że może to być dobry krok w stronę udoskonalenia kodu również jeśli nie korzystasz z Domain Driven Design.
Podczas prezentacji postaram się na konkretnych przykładach pokazać czym jest Value Object, czym różni się od Data Transfer Object oraz Encji. Zobaczysz jak łatwo używać Value Object z formularzami Symfony, jak zapisać je do bazy danych za pomocą Doctrine, jakie dodatkowe korzyści otrzymujemy korzystając z Value Object oraz jak łatwo możemy je testować.
Wskażę również czym w kontekście Value Object są named constructors oraz postaram się odpowiedzieć na pytanie, czy tworząc złożone Value Object lepiej użyć dziedziczenia czy kompozycji. Opowiem również o sytuacjach w których nie należy korzystać na siłę z Value Object.
Ze względu na dużą popularność DDD możemy bez problemu znaleźć najpopularniejsze Value Object gotowe do użycia. Na koniec podzielę się informacją, gdzie możemy znaleźć najbardziej przydatne repozytoria Value Object.

Discovering unknown with Event Storming
Mariusz Gil 1h

Event Storming is a lightweight discovery and collaborative learning tool for exploring complex domains and problems. Using Events, the first-class citizens of modern software development, in very short period of the time we can discover, model and visualize flows, aggregates, bounded contexts, business rules and related hotspots, commands, read-models… Event Storming is also a communication platform and knowledge transfer tool you may apply to release into production proper developer’s understanding of the problem, not assumptions or speculations.

During this talk you will learn about Event Storming core concepts, patterns and best-practices you may apply in your next complex project. You will also learn how to use Event Storming on different levels, from big-picture system overview to designing aggregates, commands and merging output of Event Storming session with CQRS, Event Sourcing and Domain Driven Designs implementations.

Introduction to PHP Extensions
Derick Rethans 1h

In this presentation, we take a first look at writing PHP extensions. Using
step-by-step examples, we'll take a function written in PHP and convert them
into a loadable extension using C. We'll then test both versions and compare
the results. After seeing the size and scope of the benefits that can be
realized with only a few minor changes, you'll want to try it out for
yourself. You'll also understand why we start with simple things, and not try
to rewrite all of Symfony in C.

ElasticSearch jako baza danych. Jak radzić sobie z zapisaniem i przeszukiwaniem 10mld+ wiadomości
Tomasz Banasiak 1h

Jak podejść do tematu przechowywania dużych zbiorów danych w momencie kiedy musimy zachować bardzo wysoką wydajność jednocześnie zapewniając absolutne bezpieczeństwo danych i pewność ich przechowywania. W tym kontekście opowiem trochę o ElasticSearch oraz otoczce zbudowanej przez nas wokół tej technologii. W prezentacji z pogranicza architektury aplikacji pokażę jak ugryźliśmy ten temat i co z tego wyniknęło.

Modern Testing with Codeception: Tips and Tricks
Michael Bodnarchuk 1h

Codeception is a full stack testing framework. It is widely used by various PHP companies (3+ million downloads on Packagist). What does it offer to you and how can it improve your testing experience? Codeception has smooth integration with all PHP frameworks and provides a clean DSL for scenario-driven testing. You will learn how to make:

* user-driven web site tests with Codeception and Selenium
* how to organize complex tests with PageObjects and StepObjects
* how to write and execute feature files (BDD) with Codeception
* how to test web applications effectively
* what makes a perfect API test
* how to extend Codeception

IoC containers beyond constructor injection
Hannes Van De Vreken 1h

Did you know your IoC container can do a whole lot more than just constructor injection? Besides that it is actually packed with features. Inflectors, resolving callbacks, aliasing, method invocation to name a few. In this talk you will learn how to leverage the power of a great container and service providers to write better, loosely coupled code. Well designed code put together by your IoC container will make your applications SOLID, modular, lean and decoupled from the framework!

How to double your team performance? Let’s talk about headless and API first approach.
Chris Ozog 1h

More and more projects are built using JavaScript frameworks that rely on APIs for data storage.
In this speech I will talk about the Codesushi way of developing projects that can boost a team performance.

Main elements of the talk:
- stages of the project
- tools that we used during the design stage
- description of a project where we used this methodology [case study]

Why Is CRUD a Bad Idea?
Rostislav Vítek 1h

Everyone knows what CRUD means - Create, Read, Update and Delete... But wait what is actually an Update? Does writer “update” an article or does he “publish” it? Do customers “update” an order or do they “pay” for it? Does your happy boss “update” your salary or does she “raise” it? Generic CRUD approach does not represent a real-life experience and makes both your user interface and API harder to understand and maintain. This talk covers differences between Rich Domain Model and Anemic Domain Model, their advantages and disadvantages, and how these concepts affect the design of your model, forms and user interface.

Modeling complex processes and time with Saga pattern
Mariusz Gil 1h

Time modeling is always difficult, as well as implementing business flows inside complex domains. Long lived transactions which span multiple bounded contexts, possible success and failure scenarios are even more difficult to model, test and implement. Fortunately, we have an answer to this problem! Multiple messages, events, aggregates and bounded contexts? Not a problem, Saga pattern may be very helpful… During this talk you will learn how to model long running business processes which affect many regions inside domains, what are the best possible use-cases and when to avoid sagas.

Constantly improve your PHP code
Arkadiusz Kondas 1h

Podczas testowania aplikacji PHP niezależnie od tego, czy ręcznie, czy też automatycznie, programiści spędzają wiele czasu na wykrywaniu błędów w kodzie, który nawet nie byłyby kompilowany w innych językach. W ten sposób pozostawiają mniej czasu na testowanie rzeczywistej logiki biznesowej, która powinna być najważniejsza. Dzięki statycznie analizie kodu powstało szereg ciekawych narzędzi pozwalających w pełni zautomatyzować proces Continuous Improvement. Ta prezentacje będzie obiektywnym przeglądem najnowszych rozwiązań pozwalających na stałe ulepszanie jakości kodu w Waszych projektach.

Mikroserwisy nie są lekiem na całe zło
Maciej Malarz 1h

Ale mikroserwisy są najważniejszym wynalazkiem od czasów koła! Na pewno musisz ich użyć, Amazon ma ich mnóstwo i tylko popatrz na nich. Chyba nie muszę nawet wspominać o takich tuzach jak Google czy Netflix?

Prawda jednak jest taka, że (zazwyczaj) nie jesteśmy Amazonem, skala na którą operujemy jest ciut mniejsza. Nawet problemy, z którymi codziennie się mierzymy, są z zupełnie innego typu. Mimo wszystko, ignorowanie mikroserwisów nie byłoby najmądrzejsze, więc podczas prezentacji przyjrzymy się zarówno im, jak i problemom które obiecują rozwiązać. Większej reklamy im robić nie będę, to nie jest ten typ prezentacji, po której siądziecie do komputera i zaczniecie kodzić. To jest ten typ prezentacji, po której pomyślicie dwa razy zanim dacie się porwać hype'owi. Zamiast koncentrować się na zaletach, przyjrzymy się balastowi, jaki towarzyszy mikroserwisom, oraz zastanowimy się czy gra jest w ogóle warta świeczki.

It's all about the goto
Derick Rethans 1h

Don't worry, this is not about the goto keyword.

In this presentation, I am showing you some of the inner workings of PHP. We
are going to look at how different language keywords and constructs are handled
internally. Basically, everything is converted to goto, but the how and why, is
not as simple as it seems!

This is a very in depth talk, mostly interesting to people that want to know
how PHP works internally. Expect lots of wonkyness, a form of assembly, and

PHP + Business = Money!
Martin Hlavač 1h

PHP isn't sexy anymore and that's why we love it!
This is a story of mature language that drives huge businesses, generating billions in revenue. At Wayfair we use mostly PHP and we try to stay pragmatic about it, avoiding dogmas by always evaluating pros and cons of our decisions. Keeping things simple with 1000+ engineers isn't easy. I'll share with you our magic formula and few insights that will make your decisions more pragmatic, helping you run your own business.

Journey through "unhappy path" - Dealing with exceptional conditions
Nikola Poša 1h

Developers naturally gravitate towards the "happy path" - default scenario in application execution in which everything works as expected, consequently neglecting exceptions and error handling aspect of a software development. This talk provides a comprehensive insight into widely adopted practices and patterns for dealing with exceptional and error conditions. You will learn about writing and organizing custom exception classes, formatting exception messages, component-level exceptions technique, and much more. In a word - Exceptions cheat-sheet. Once thrown, the exceptions should be caught, so you'll also be introduced with different error handling strategies and concepts.

Getting started with PHP core development
Arnout Boks 1h

While PHP’s open source community is thriving, only a relatively small number of PHP developers contribute to the number one tool they use on a daily basis: PHP itself. Although it may seem daunting to help out on a project written in C, requiring compilation and linking, getting started is actually pretty easy.
In this talk I would like to share my own recent experiences of beginning to contribute to PHP itself. We will cover some practical tips, workflows and resources, so you can start giving back to your programming language straight away!

How we break things at Wayfair
Roberto Ladd 1h

In a hyper growth company with over a thousand engineers collaborating every day things will eventually break. How can this single assumption be a success driver?

Code Review - jak robić to lepiej?
Sebastian Malaca 1h

Im bardziej skomplikowana jest aplikacja, tym więcej osób nad nią pracuje. Im więcej kodu tworzą programiści, tym ważniejsze jest dbanie o jego jakość. I w tym momencie przychodzi nam z pomocą Code Review.
Jednak, często zdarza się, że po jakimś czasie, kiedy chęć ludzi do wypróbowania tej techniki maleje, a ilość review rośnie, wiele osób zaczyna narzekać. Szukają wymówek, aby tylko nie robić review. Albo nie robić ich wystarczająco dokładnie.
Czy to jest problem? Tylko jeżeli w tym momencie nikt nie zareaguje. Ponieważ tak naprawdę jest to chwila na wprowadzenie usprawnień i poprawek!

Start Smoking, Get Confidence - HTTP Smoke Testing
Petr Heinz 1h

It is usually not easy to start with automatic testing of an existing web application. You may have heard that applications must be written to be “testable”. But what if you still want the confidence that your refactoring did not cause the application to crash? And even if your application is testable that does not stop you or other people from skipping writing tests in order to “save” some time because let’s face it - the application can be used even without automatic tests.
We will present you our package for HTTP smoke testing that:
- makes it easy to start with testing any Symfony web application
- will automatically prompt you to test new pages/actions
- is so cheap to use that you will not even think about skipping writing tests

Constructing a Test Pyramid: Because Your Tests Needs Architecture Too
Michael Bodnarchuk 1h

Every PHP application needs its policy about tests. What is important to test, what is not, at which levels should a feature be tested. As we think of application architecture before writing a single line of code, we should think of a test architecture before implementing tests.

From this talk you will learn:

* how to transform business expectations to tests using ATDD and BDD approaches
* how to write stable tests that evolve with code
* how to deal with test data
* how to decide, should it be unit or integration test

Coffee break
Migracja danych - case study
Piotr Kosinski 1h

Kiedy dwie firmy się łączą, developerzy stoją przed wyzwaniem integracji systemów oraz migracji danych. Tak się stało kiedy eMAG - jeden z głównych graczy na rynku e-commerce w Europie środkowo-wschodniej - zdecydował się na migrację systemów przejętej firmy do swojego ekosystemu. Nasze zespoły miały możliwość pracy nad migracją dużej ilości informacji - danych kilku milionów produktów do naszych systemów. Brzmi banalnie - "weź produkt z aplikacji, dostosuj i zapisz w naszej aplikacji". Chcielibyśmy żeby tak właśnie było ;-) Opowiem Wam naszą historię: jakie problemy napotkaliśmy, co zrobiliśmy dobrze oraz gdzie popełniliśmy błędy - pamiętajcie że najlepiej uczyć się na cudzych błędach! Moja prezentacja obejmie tematy z obszarów analizy biznesowej, rozwiązań technicznych oraz zarządzania.

How we handle integrations of more than 100 different partners?
Umit Akkaya 1h

Having many partners is an amazing thing. What about integrating with them?
You have to
- Provide implementations for REST APIs, SOAP services, non-standard web services.
- Support different authentication methods
- Handle errors in case of a failure in third party system
- Last but not least each side has to be aware of every change.

In this presentation I will show you how we tackle all those problems within our architecture by creating a centralised integration application. Our solution heavily relies on the following techniques and technologies:
- Message Queue
- Command/Event bus
- API Callbacks for realtime events

Introduction to the Semantic Web
Arnout Boks 1h

What if we could evolve our web of individual documents and data to a web of interlinked knowledge, a web where machines can automatically combine data from multiple sources and draw conclusions from it?
The Semantic Web technologies from W3C enable us to make sense of the data wilderness on the web and unlock the full potential of the data treasures hidden in it. In this talk, we will see how RDF enables us to formally describe the meaning of data and how such data can be queried with SPARQL. We will look at how OWL lets us make more expressive statements about the world, so that a computer can logically reason about it and infer new information. We will demonstrate these technologies by showing how they can be used to combine data sets in different formats as if they were one and letting a computer draw logical (and perhaps surprising) conclusions for us.

Easy Coding Stadard - Setup Coding Standards under 5 minutes
Tomaš Votruba 30m

I educate companies about advantages of coding-standards when it comes to hiring new people, code-review smells and upgrading to newer version of framework.

When I explained developer PHP_CodeSniffer and PHP-CS-Fixer I often saw, it's too complicated for them. I realized, I'm so used to them, I don't see the huge entry barrier I had many years ago too.

I don't want programmers to put energy to learn complicated things, that are very simple in their essence. That makes me really angry!

So I took a year off and made a tool, where all you need is one CLI line.
I named it EasyCodingStandard. It focuses on open and clear communication, what is happenening, which class is doing what check and guides you what you should do. Did I say it supports own checkers and uses cache, that finishes 2nd run under few seconds?

Uncommon (Ab)Uses of Composer
Alain Schlesser 1h

Composer is a hugely flexible tool that works reliably on all but the most obscure hosters/platforms. What's more, it provides a plugin system that lets you pull external code from a repository and have that code hook into the normal Composer execution flow. The logical conclusion is that Composer is used for much more than just pulling in dependencies.

We'll start this session with a quick look at the basic mechanisms that make Composer as flexible as it is. Then, we'll go through some of the more useful and/or exotic examples of how to use Composer for solving problems that it wasn't really meant to solve.

Event Sourcing - historia pewnej encji
Jakub Saleniuk 1h

Event Sourcing, dzięki swoim zaletom, w ciągu ostatnich kilku lat zyskał bardzo na popularności. W mojej prezentacji przybliżę ten temat osobom, które chcą rozpocząć programować według nowego podejścia. Dodatkowo poruszę bardziej zaawansowane kwestie jak wersjonowanie eventów, tworzenie projekcji oraz integracja z zewnętrznymi systemami w Event Sourcing.

Jakie są koszta hostingu na AWS?
Krzysztof Daniel 30m

To pytanie pojawia się często, kiedy pada propozycja uruchomienia projektu na AWS.

Podczas prezentacji pokażę parę casów odrobinę bliższych polskiej rzeczywistości (hostowanie średnich projektów, nie Neflixa czy innych ogromnych startupów) i średnich kosztów automatycznie skalowanej infrastruktury, które dla wielu jest rozwiązaniem na nieograniczony skalowanie horyzontalne i problemy z wydajnością.

Przedstawię kilka wskazówek na temat kosztów, pułapek abyście mogli wyciągnąć wnioski z naszych wpadek. Pokażę, jak my pracujemy ze środowiskami automatycznie się skalującymi, jak je konfigurujemy i jaka jest nasza strategia na rolling update. Jakie opcjonalne założenia musimy poczynić, kiedy wśród wymogów pojawia się wysoka dostępność.

Ostatecznie postaram się odpowiedzieć na pytanie czy AWS pozawala zaoszczędzić pieniądze na hostingu?

Opowieść o podłączaniu sprzętu przemysłowego do serwerów z PHP.

Async PHP requests & reactive responses with php-fpm
Holger Woltersdorf 1h

There are many approaches to execute PHP sub-tasks asynchronously or to parallelise PHP execution.
While some solutions require extra extensions, individual PHP builds or a lot of process control management, this talk will show you how to configure and use the built-in PHP FastCGI Process Manager (php-fpm) to execute requests asynchronously in an isolated, tunable process pool and eventually handle their responses in a reactive way.

Diving deep into blockchain
Tomasz Kowalczyk 1h

The blockchain is a hot new topic in the technology due to the rise of various cryptocurrencies, Bitcoin being a most prominent example. How does it work? What advantages does it give? What problems do they solve? What problems can be solved that way? I want you to dive with me into the immutable world of blocks where I will explain everything, from a simple hash, through Merkle trees, up to implementing your own blockchain.

Blockchain to technologia, która stała się popularna dzięki najpopularniejszej kryptowalucie - Bitcoinowi. To idea bazy danych, w której raz umieszczone dane nie mogą się już zmienić. Te właściwości powodują, że wiele branż zainteresowało się przechowywaniem swoich danych w blockchainie. W tej prelekcji przedstawię ideę blockchainu, techniczne mechanizmy i algorytmy, które umożliwiają jego poprawne działanie oraz pokażę w jaki sposób działają istniejące implementacje blockchainu.

Simple Plugin Creation in WordPress
Peter MacIntyre 1h

Can't find that perfect plugin in the thousands that exist?
Do you want to extend an existing Theme? Come to this session
to see just how easy it is to create your own plugin and to
get a brief look at the internal functions that WordPress makes
available to the developer. We will actually create a simple
plugin and a child theme in this session while looking at the
PHP code needed to make this happen.

Middleware-based architectures
Matthieu Napoli 1h

HTTP middlewares are spreading everywhere since PSR-7, yet they are often seen as an implementation detail for very specific problems.

After having discovered them with PSR-7, after having written a middleware-based framework and after collaborating on PSR-15, my understanding is now different: middlewares help us better understand and design the architecture of our applications.

Let's start again from scratch and work our way up to an architecture entirely built on middlewares: what does it look like and how does it compare to the frameworks we all love?

Microservices vs The Distributed Monolith
Christopher Riley 1h

When faced with a challenging legacy code base, tightly coupled and void of discernible structure: a big ball of mud, it is common to decide to refactor this monolith to a microservice architecture to separate concerns and split the codebase up, however without any clear boundaries you are in danger of creating a distributed big ball of mud.

You may recognise the symptoms of a distributed ball of mud: a large unfocused 'common' library shared between multiple services; performance issues as your front end makes calls to multiple back end API's to serve a single request; dependency hell on deployments as you have to release multiple code bases simultaneously and uptime issues as a single microservice going down brings down your entire application.

In this talk I'm going to cover some of the common pitfalls you might encounter when building a microservice architecture and show you how to use an event driven architecture to build truly scalable microservices.

Building an Open-Source Campaign Platform for the new President of France
Hugo Hamon 1h

This case study will take you to the technical backdrop of Emmanuel Macron's victorious campaign in the French presidential elections of 2017. We will reveal how the En-Marche and SensioLabs teams worked closely together to develop a collaborative, Open-Source and citizen platform with PHP 7 and Symfony to structure the movement. In addition to the technical and political issues involved in this project, we'll present solutions such as continuous deployment with Docker under Kubernetes, continuous integration with Circle CI, SCRUM and Kanban project management, use of Rabbitmq, Symfony 3 new features, and more. We'll demonstrate the importance of choosing these solutions to meet the agility and scalability needs of the highlights of the campaign.

What we learned by merging two big Symfony based applications
Ivo Lukač 1h

Due to complex web projects we work on, there was a need for deeper integration between content management system and eCommerce solution. As eZ Platform is based on Symfony we searched for a Symfony based ecommerce solution and found Sylius as the best choice.
We combined the two systems in one Symfony instance so we can integrate on much deeper level. Learn about our experience with merging and maintaining such a solution.

Time-driven applications
Piotr Horzycki 1h

Discount systems, booking platforms, contests - all those applications have one thing in common: date & time management. How to implement business logic dependent on the time of the day, week, year? Half-price pizza on Mondays, course registration until the end of August or a landing page available only in November?

I deal with business requirements like these every day at work. I will show you the way I refactored messy code and wrote tests, so other programmers would not be afraid to make changes anymore. I'll convince you to use DateTimeImmutable and show some interesting date/time operations available in PHP standard library.

UUID - The only ID you need?
Arkadiusz Kondas 1h

Co to jest UUID i co oznaczają kolejne jego wersje? Jak zacząć korzystać z UUID w PHP? Czy moja baza poradzi sobie z UUID? Do czego nadaje się UUID, a do czego nie? Czy UUID to jedyne ID jakiego potrzebuję? Na te i inne pytania postaram się odpowiedź w prezentacji poświęconej wyłącznie uniwersalnie unikalnym identyfikatorom.

Wnioski z umieszczenia skomplikowanego systemu w kontenerach
Grzegorz Drozd 1h

Czego nauczyliśmy się umieszczając w kontenerach aplikacje w Perlu i PHP która używa MySQL, Solr, ElasticSearch, Cassandra, AWS i przetwarzania w tle. Wszystkie się zmieściły.

Infrastructure as Code
Sebastian Grodzicki 1h

Terraform enables you to safely and predictably create, change, and improve production infrastructure. It is an open source tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned. Terraform has emerged as a key player in the DevOps world for defining, launching, and managing infrastructure as code (IAC) across a variety of cloud and virtualization platforms, including AWS, Google Cloud, and Azure. In this talk I'll show you how to get up and running with Terraform using IaaS (e.g. AWS, DigitalOcean) or SaaS providers (e.g. CloudFlare, GitHub).

If you are not a confirmed speaker, your ticket does not have bed and breakfast included. We were promised that all the rooms in the Ossa hotel will be for our disposal only. Keeping in mind that there's more conference tickets than accommodation, the best solution is to book B&B first. You can stay in the Ossa or any hotel nearby.

Blind Bird tickets are offered before announcing the agenda and gives you access to the same services as Standard ones, but these tickets are intended especially for students and persons in worse financial condition, not for groups. If you want to buy group ticket for your company team, we suggest to choose rather Standard Tickets, due to limited amount of Blind Birds.

Note, that payments for tickets below are in Euros. If you'd like to pay in Polish Zlotys (PLN) or your company has a NIP (Polish tax id number) please change the language of this webpage to Polish first.
