DynamicWebPages.de has posted some information about PHP's presence at this year's LinuxTag Conference where there will be no official PHP track, but will be several PHP-related talks.
Even if this year there's not an emphasis on PHP, developers can find a few lectures that might grab their interest. Peter Prochaska and Christopher Kunz of the Hardend PHP project will talk on the latest trends in web hacks (May 4th), Tobias Hauser and Christian Wenz will look at Open Source Ajax (May 5th), and Derick Rethans will give a talk on PHP6 and Unicode (May 6th).
