As posted on the Zend Developer Zone today, Zend has issued their Call for Papers for this year's Zend/PHP Conference and Expo happening this September at the Santa Clara Convention Center.

Zend invites submissions to the Zend/PHP Conference and Expo, ZendCon08, which will be held September 15-18 at the Santa Clara Convention Center.

This year's conference program will include competitively selected presentations, tutorials, and invited speakers. All sessions undergo a peer review process by the ZendCon Content Review team.

There's a few different tracks this year including "The Basics of PHP", "Performance and Scalability", "Zend Framework" and several vendor presentations. You can find out more about the requirements and where to send your presentation on this page on the ZendCon 2008 website. The deadline for submissions is midnight on April 30th, 2008 so you better get busy preparing and sending it in!

Sebastian Bergmann has posted about this year's FrOSCon 2008 and the Call for Papers they've issued:

Focus of the conference is a comprehensive range of talks about current topics in Free Software and Open Source. Furthermore, space will be provided for developers of free software and open source projects to organize their own developer meetings or even their own program.

This year will be the third annual FrOSCon and will be held near Bonn, Germany. Besides the main conference, there will also be a sub-conference that has a Call for Papers of its own.
