The "it works on my machine" mentality has resulted in numerous face palm moments. This is even more painful when a your app is under heavy load due to a marketing campaign. With some minimal code changes and some smart utilities, you can maximize your scalability and performance. Keywords: Varnish, PHP-FPM, Nginx, APC, CDN, Gearman, Memcached and a proper server setup. I'll show you how you can make a slow app with a crappy code base go mighty fast on one and even multiple servers. The focus of this talk is to cure first and eventually learn and prevent.

Continuous Integration has typically been a practice only performed by companies who want that piece of mind for their client software, but does it need to be like this? Travis CI is a continuous integration service for the open source community. We make testing OS projects dead simple and fun. But most importantly, we help improve code quality for large projects like Doctrine2 and symfony, to smaller libraries like FOSRest. The vision behind Travis CI is to become for builds what PEAR is for distributing libraries. In this talk Josh, one of the core members of the Travis CI team, will introduce you to the vision behind Travis, the how it is implemented, and why it matters to everyone in the OS community.

The standard PHP library (SPL) is growing in both maturity and use. But a lot of developers still aren't aware of the tools in SPL or simply haven't seen good examples of how to use the code. From interfaces to an autoload stack to classes that make objects act like arrays, there are tools to make every application leaner and faster, or simply more clever. Using live projects from github, take a look at the good, bad, and the ugly of SPL usage in PHP development.

In this talk we will present a simple web application built with Zend Framework 2. We will show the new features of the framework, such as the new MVC layer, the Event Manager, the Dependency Injection and much more. The aim of this talk is how to start programming with the new architecture of ZF2. Moreover, we will show the differences with the version 1 of the framework and how to migrate applications from ZF1 to ZF2.

During this talk an introduction will be given to parsing. Terms like 'formal grammar', 'lexing / scanning', 'LL / LALR / PEG' will be explained and put into context. We will look at a recursive descent parsing as a practical way to parse languages. Finally the audience will be left with ways to get started with parsing structured text into memory.

Good news! We've managed to acquire a conference ticket for the Dutch PHP Conference in Amsterdam, on June 8th and 9th, to give away to our readers. We know that since you're reading techPortal, you are interested in technology in general and probably PHP in particular. The Dutch PHP Conference is one of the leading european conferences for PHP content and we hope you can join us there!

The ticket to this year's Conference also includes admittance into the Dutch Mobile Conference if you're interested in that as well. You can find out more about the Dutch PHP Conference on the main event site.

Cal's "three questions" during the interview relate to

• What pushed you into wanting to speak at a user group?
• As a speaker, what advice do you have for people wanting to get started at user groups or conferences?
• As an organizer, has your perspective on speaking changed? What advice do you have for people to get to the conference level?
