In late 2016, Jenkins finally made it to version 2.0 which brought a huge number of improvements. In this talk, we’ll go from an empty machine to a Jenkins install that automatically detects repos, branches and pull requests and builds them according to the Jenkinsfile in each branch. We’ll be running tests, linting and packaging applications in parallel where possible, and even auto-deploying our application once our pipeline passes!

Do you want to build an API? You’re not alone. Several tools exist to help you prototype an API with minimal effort on your part. In this talk, we’ll make use of PHP and Laravel’s Lumen framework to build an API using all of the bells and whistles of a framework without all of the full stack stuff we don’t need. By the time attendees leave this talk, they’ll have an overview of how they can use Lumen to create an API that they’ll love maintaining and that users will love using. They’ll also have an overview of API design best practices as well as a sprinkling of service-oriented architecture.

In an increasingly connected world, APIs are key to great tools and effective workflows. What is better than an API? A webhook of course! Webhooks are a key building block of a modern application, allowing systems to exchange data in response to events. This session gives examples of webhooks currently in use ““in the wild””, and examines both when a webhook is useful and the internal design and structuring of webhook payloads. We’ll discuss how to work with webhooks in a scalable way regardless of technology stack; how to recieve and process incoming webhooks from an external system and how to design and publish your own for use by partners or consumers. Recommended for anyone wanting to teach their applications to play nicely with others.

Since GraphQL was announced by Facebook in 2015 it has started to gain quite a bit of traction with many companies such as Github looking to adopt it to either replace or complement their existing REST APIs. GraphQL provides a powerful way for the frontend to be able to query data sources and your business logic, giving and receiving only the data that they need, without having to always have custom designed endpoints for every use-case. As a consumer of third party APIs it probably won’t be long before you’re consuming a GraphQL API; and as a designer or creator of APIs, GraphQL can sometimes provide a better alternative than a REST API. Join me for a tour of what GraphQL looks like, what it works well for, how to consume a GraphQL API, and how to easily design and create one in PHP.

When people talk about Doctrine (or any ORM for that matter), the performance issue always comes up fairly quickly. Besides the fact that Doctrine will help you develop faster, so a little overhead doesn’t really matter, there are numerous options to increase the performance of the application. By understanding how the system works in the first place, a lot of issues can be avoided right away. When you have done everything to avoid these pitfalls, you can bring in the big guns: caching. Doctrine has different caching mechanism and since Doctrine 2.5 “Second Level Cache” was added to our toolbox. After this talk, you should know what the impact is of every cache and how to use it.

Unsure where to start with your next application? Are you sure you want full stack Symfony eventually but not sure you can commit to the extra work upfront? Afraid if you start with a micro-framework like Silex you’ll end up needing to migrate to full stack Symfony anyway? Enter Symfony Flex. Symfony flex brings all of the power of full stack Symfony with the upfront requirements of a micro-framework. Choosing Symfony upfront not longer commits you to the overhead you might expect from a traditional Symfony project. See how quickly a new project can be started and how it can evolve over time.

Using event dispatchers and command buses in applications is becoming common place, but are we using them in a way that aids understanding? With the rise in popularity of Domain-Driven Design to drive meaning in applications, and our applications becoming increasingly small and “hexagonal”, the concept of defining the difference between an Event and a Command is becoming more important. This talk explores using command buses and event dispatchers in combination to clearly segregate the structure, and uses an example of how to use these to create clean CQRS-based applications.

PHP’s stateless execution model is still based on the mechanics of CGI: request in, response out. This simplicity also means overhead on each request from frameworks starting up; applications also cannot interact with the request body during transmission, e.g. for streaming the body or handling upgrades to Websockets. That’s why all other web languages now offer production ready web servers implemented purely in each language: Jetty, Puma, Gunicorn and friends use a modern process model and standardized middleware protocols. PHP 7 finally brought some necessary engine changes like catchable fatal errors, so there now is no longer a need for Apache or Nginx: event based HTTP components from projects like ReactPHP or Icicle, brought together by a server like Aerys or PHP-PM, start a framework once, and handle requests in a loop. The result is a massive gain in performance especially with frameworks like Symfony, and the potential for new features that previously were not possible with an external web server in front of an application. Let’s explore the current state of affairs, the solutions other programming languages found, and the bright new future that’s ahead for PHP, which, as always, will require sacrifices to be made.

In this talk we present Json Web Tokens as an alternative for smart and self contained tokens, explaining how to use each claim and giving some common use cases.

It’s a situation many of us are familiar with: a large legacy, monolithic application, limited or no tests, slow & manual release process, low velocity, no confidence… A lot of refactoring is required, but management keeps pushing for new features. How to proceed? Using examples and lessons learned from a real-world case, I’ll show you how to replace a legacy application with a modern service-oriented architecture and build a continuous integration and deployment pipeline to deliver value from the first sprint. On the way, we’ll take a look at the process, automated testing, monitoring, master/trunk based development and various tips and best practices.

Static analysis tools checks PHP code without running them. Fully automated, they bring expertise to review the code, enforce good practices when programming, keep code ready for the next PHP version. PHP 7 has developed tremendously our capacity to audit code - thanks to AST and return types, it is possible to go deeper and prevent more bugs. During this session, we’ll review the current state of static analysis tools, learn what they can find for us, and how to integrate it in the development cycle - security bugs, migration incompatibilities, directives recommendations. Simply said, better PHP coding.

High availability is becoming a de-facto requirement of today’s applications. Customer-facing IT failures mean directly losing customer revenue and trust, as users have grown accustomed to easily switching service providers for more reliable ones. Lack of internal systems availability block employee productivity and add to the financial burden. Thus, it is critical to have a healthy, performant, resilient IT structure serving as a backbone of conducting your business. But there are no textbook solutions to achieving five 9s availability. Data redundancy, computing clusters, load balancing, fail-over mechanisms, each of these individually addresses one potential issue, but none treats systems in your organisation holistically for maximising business revenue. Silos are a clever method of grouping servers in such a way that they can be scaled both horizontally and vertically, depending on the actual application needs. Most importantly, it frees you from over-optimizing the architecture upfront, by allowing fine adjustments easy to integrate in your Agile workflow.

You’ve written an application and now the worst thing that can happen to you has come about - People are using it! You now have load spikes to deal with. You can scale up to deal with the excess traffic, but what do you do when your load is variable? How do you do that, and stay on budget? This session is a case study on getting an App Engine app to scale to serve 30,000,000 requests an hour. It will take you through the architecture, the code changes and the technology trade offs to get to that level of traffic. And how to make sure your app scales down so running infrastructure to deal with potential traffic doesn’t drown you.

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.

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.

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.

Reports of the death of TDD have been greatly exaggerated.

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.

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”.

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.
