If you’ve done any interesting work in PHP, this is your chance to show it off to 100s of PHP developers and students (actually the number has been known to even go up to 1000). If your company is doing cool PHP work, then the easiest way to attract star PHP developers is to give a talk at PHPCamp.
PHPCamp is a “barcamp” for PHP developers and enthusiasts. It is basically an unorganized conference where anybody can attend, it is free and open to all, and anybody can register to be a speaker.
