There will be a LAMP Area again at this year's LinuxTag, which will take place in Karlsruhe, Germany from June 22 to June 25.
June 23 will be the "LAMP Day": a full day of presentations covering the state of the world that is Apache, MySQL, and PHP.
I will give a presentation titled "PHP 5 - Ein Jahr danach" which will give an overview of software packages that were ported from Java to PHP 5 in the year after the release of PHP 5: PHPUnit2, Phing, Creole, and Propel.
