New on the Ibuildings techPortal site the latest episode of their DPCRadio podcast series has been posted (as recorded at the Dutch PHP Conference 2010). This episode is Johannes Schluter's talk "Under PHP's Hood".

PHP developers usually don’t have to care about the inner workings of PHP and the Zend Engine as it simply works. This presentation will present some of the inner workings, like teaching the truth about references. Additionally it will present basics of PHP’s opcode, the internal representation of a script, and it’s consequences for opcode caching, autoloading and other related issues.

As always, you can either listen via the in-page player or you can download it and listen later.

Pierre has put a call out for PHP developers who would like to participate in a TestFest event to be held in Munich (and southern Germany).

Johannes and I are trying to organize one or more TestFest days. No PHP internal knowledge is required (like C knowledges), all you need is willing to help to improve PHP and a good mood.

If you'd like to participate, contact either Pierre (pierre at php dot net) or Johannes (johannes on php dot net) and they'll get in touch. If you're wondering what the TestFest is all about, checj out this page off the main PHP.net site for more information.

On his blog, Johannes Schluter has posted about the participation that the Munich area will have in the upcoming TestFest:

The PHP TestFest was mentioned on Planet PHP multiple times before, so let's make it one more: Pierre and me are currently working on organizing a TestFest event at Munich. So we are looking for feedback from folks somewhere in the Munich area (or even all of southern Germany) so we know how many people to expect and then set a date.

You can get the latest about the TestFest from its page on PHP's QA site and the wiki page for all of the details (including groups that might be in your area participating).
