Zend has announce the official opening of the Call for Papers for ZendCon 2015, their annual PHP and technology conference. Instead of their usual venue in California, though, they'll be holding the event in Las Vegas, Nevada from October 19th through the 22nd.

We’re pleased to announce the ZendCon 2015 PHP Conference, the most anticipated PHP centric event of the year, where community and enterprise PHP developers from around the world gather to share and learn the latest hot trends and technologies in today's professional PHP development.

We know speakers are key to the success of a conference and hope you will submit a talk. In appreciation for the efforts provided, our speakers package ensures they will not need to worry about anything other than delivering the best talks.

While ZendCon is put on by Zend (a company largely focused on PHP) they accept talks on more than just PHP-related topics. You can find out more about the conference in previous years (and some of the topics that were accepted) on the main conference site. The Call for Papers ends on May 15th so be sure to get those submissions in early and often!
