International PHP Conference 2011 Spring Edition impressions

I planned to post this a lot earlier, but I wanted to do the presentation at Softonic first and I am also very lazy.

My employer was so nice to send a colleague and me to the International PHP Conference 2011 Spring Edition in Berlin this year. It was a three day conference. There also was one day of workshops, which we skipped. We also skipped most of the keynotes, because most of them were in German and didn’t seem very useful.

I concentrated on the topics that interest me most: agile, unit testing, continuous integration, continuous deployment and Symfony/Doctrine. So here goes a quick summary of the stuff I think was good.

DevOps fuer PHP by Johann-Peter Hartmann slides

A very good introduction on DevOps, mostly introducing lots of tools and how they are used at Mayflower GmbH. I found especially the bits about self service virtual machines and clouds for developers interesting. They are using a combination of puppet, vagrant, fog and eucalytus for this. He also emphasized how important the culture in a company is to make this possible. All of this enables faster development and deployment. I plan to have a separate post about this soonish.

3*PHPUnit by Sebastian Bergmann

This could have easily fitted into one talk. And if you have seen any of his talks before you could have skipped most of this too. I liked the quote about removing the release cycle and making it much more fluent, reference to the etsy blog (which is brilliant) and latent code patterns. None of this is new stuff though.

MySQL, PHP - The current State by Johannes Schlueter

Oracle man. Improvements in MySQL 5.5 and 5.6. memcached interface, which is currently in labs. Some examples of the asynchronous mysqli interface, which sounds really interesting for some use cases. Also information about mysqlnd plugins, especially the mysqlnd_uh one which allows writing these in PHP. All of this is not so useful if you like your ORMs though.

Large-Scale Data Processing with Hadoop and PHP by David Z├╝lke slides

Highly recommended if you can see this at any conference. Very good presentation, starting with the use cases of sites which are producing lots of data and need to use map reduce to mine it. It continued with a live demo on a laptop, first tuning it until the speed increased by using map reduce and later connecting two laptops to show how well it scales.

Next Generation API Documentation by Arne Blankerts

I didn’t expect much of this last talk, but it turned out to be pretty good. As PHPDocumentor seems to be pretty dead, there is a need for a new system. CI systems usually also generate the API documentation, so it is important that this is also fast. phpdox seems to solve this, but it is still in an alpha stage so we have to wait and see.


I also saw a lot of other talks, but most of them were either introductions to things like node.js, nginx, JavaScript QA, Doctrine NoSQL and Symfony CMF. None of these contained any new information for me. Sometimes I wonder I should stop reading blogs and twitter two months before a conference, just to make them morei nteresting.
