The PHP world is spinning quite fast these days. There’s a lot to keep up with. You can’t be an expert in all subjects, so you need a way to find out what’s relevant for you and your team. Which approaches to software development would be useful? Which programming paradigms could help you write better code? And which architectural styles will help your application to survive in this quickly changing world?
In this talk I’ll help you answer these questions by taking a bird’s-eye view. I will quickly guide you along some of the most fascinating topics in modern PHP development: DDD, BDD, TDD, hexagonal architecture, CQRS, event sourcing and micro-services. We’ll see how these things are related to each other, and how understanding and applying them can help you improve your software projects in many ways.

A good rule of thumb to have as a developer is that if you have to do something three times or more, you should automate it.
Imagine that a task takes you a minute to do, twice a day. Now imagine that you could write something that does it for you, but it would take an hour. Initially, you’ll have lost an hour, but after the first month you’ll be breaking even, as you’ve saved those two minutes per day. Then after the second month, you’ve essentially gained a free hour.
Automation is a developer’s best friend. Some things are easier to automate than others, but almost anything can be automated. In this talk, we’ll take a look at what can be automated, what tools are available to help us and crucially, if we should automate it. Surprisingly, sometimes the answer to the question “should we?” is “no”.

Security is an enormous topic, and it’s really, really complicated. If you’re not careful, you’ll find yourself vulnerable to any number of attacks which you definitely don’t want to be on the receiving end of. This talk will give you just a taster of the vast array of things there is to know about security in modern web applications, such as writing secure PHP web applications and securing a Linux server. Whether you are writing anything beyond a basic brochure website, or even developing a complicated business web application, this talk will give you insights to some of the things you need to be aware of.

Docker has recently been one of the hottest words in the web technology world. But why is it so? Isn’t it just another “hyper tool” that will be forgotten in a year?
I’ve been using Docker for one year to develop and deploy both professional and pet projects. During this year I worked out my very own set of best practices to deal with Docker, that I’d like to share with you.
Why is Docker so popular? Is it hard to use it? How to use it to develop PHP applications and how to deploy them into the cloud? What are the main threats of Docker? Is it worth to use it? If you ever thought about any of these questions, this presentation should be interesting for you.

Splitting an application up into multiple independent services can be a good way to keep it scaling and ensure stability and developer productivity in larger, growing teams. But just splitting the codebase, creating APIs and deploying the code on some servers is not enough, somehow your services need to know where and how other services are accessible. Classical approaches like hardcoding everything in every service or having a central load-balancer can quickly lead to problems in terms of scalability and maintainability. In this talk I’ll show how we at ResearchGate tackled this challenge. With the help of tools like Consul and haproxy we created a setup that allows us to quickly boot and shutdown services. This ensures that all servers are utilized optimally and load spikes can be reacted upon quickly and automatically.

When helping companies improve their development practises, there are often conceptual sticking points - for example, rebase can be hard to understand and many people are wary of it. To help us better understand and communicate our workflows, I will illustrate Git concepts in the language of comic books, followed by a practical demonstration of the techniques.
This session has something to offer all Git users - from newcomers trying to get their heads around it all, to veterans trying to communicate a workflow to their colleagues. It should certainly spark an interesting discussion!

In this talk we will discuss using HHVM and MongoDB together. In the last months I have written an HHVM extension for MongoDB, that mimics the API of a similar PHP extension. On top of each extension we have a layer in PHP that provides the more user friendly aspects of the driver. The PHP part of the driver gets accelerated to nearly the same speed as the extension written in C++, while being vastly easier to update and maintain.
We will dive in to the architecture of the whole setup, HHVM’s JIT and extension APIs as well as some comparisons between running your app on PHP+MongoDB and HHVM+MongoDB.

ZF3 is the framework that took the opportunity to learn from the previous 4 years of ZF2 and be even better than that! Today’s PHP projects are built of components installed via Composer and ZF3’s architecture reflects this approach; its core components have also been greatly improved in both usage and performance from older versions of the framework. If you’re already running a ZF2 application, you’ll be able to upgrade your existing application and there will be some excellent support for doing so - we love it when developers get to use new things. We’ll also look at how PSR-7 and middleware has been embraced. If you want to learn what’s new in the world of Zend Framework, then this session is for you.

Reports of the death of TDD have been greatly exaggerated. All but the most trivial of applications make use of the OOP principle of composition and as such require mocking of dependencies in unit tests. While PHPUnit has become the de facto unit testing framework for many projects, its bundled mocking API can leave something to be desired. This presentation is an introduction to Phake, an alternative mocking library with a more concise and intuitive API and a more substantial feature set that removes the headaches from mocking.

PSR-7 describes common interfaces for representing HTTP messages. HTTP messages are the foundation of web development. Web browsers and HTTP clients such as cURL create HTTP request messages that are sent to a web server, which provides an HTTP response message. Server-side code receives an HTTP request message, and returns an HTTP response message.
This talk will explain the interfaces defined by PSR-7, how they define the future of interoperability between frameworks and tools. After that there will be a showcase of several implementations and tools such as zend’s diactoros package, Guzzle v6, php-http and other packages that show the real power of shared interfaces for HTTP objects. As most projects are ongoing, this talk will also show how PSR-7 and these other tools can already be used today in existing projects.

This is not your normal security talk.
Sure we talk about secure communication and the importance of hashing and encrypting (and why rolling your own is never a solution). We might even get frisky and cover some more interesting topics like true randomness, timed attacks and social engineering.
But what we’re really interested in is understanding what that hacker is trying to do on your site, what the motivation is and, using this, understand where you need to be vigilant.
We’re also going to talk about the results from an ongoing 4 year project to see just how vulnerable the average consumer website is. Theodore Sturgeon famously said 90% of everything is crud, we’ll get to see just how close we come to that number.
So if you’re ready to see how scary the dark depths of security can be and just how scary it is when you look up and see all the leaky boats above us is, this is for you.

I’ve put together a run down of some of my tricks, tips and ‘good citizen’ techniques to avoid the worst kinds of conflicts and deal with the remaining ones as efficiently as possible.
Join me on a journey through some of the causes of version control pain after which we will visit some social and technical solutions. I’ll lead you via branching policies, basic conflict resolution, to more tricky conflict management. We will spend time with some of the lesser known features of version control and command line hacks to stay in charge of multiple branches.
As a bonus we will discover how version control can be integrated with other tools having many positive knock on effects for your team and wider business: How forcing commit message formats and automating your change log can help your release process or apps to streamline code reviews can avoid some unnecessary context switching. Triggered notification of interested parties helps keep everyone in the loop especially for breaking changes.
