Gilang Chandrasa has put together a list of PHP libraries the Komunitasweb.com site recommends using in your applications.

Having a collection of php libraries in one places will help you get your job done faster. It help me, so I share my list. I’ll keep update the list with more libraries.

Among those in the list are libraries like PEAR's Services_JSON, PHPUnit, My_Twitter, SimplePie and SwiftMailer.
