On Developer.com today Jason Gilmore shares nine (more) experimental PHP projects he thinks you should at least know about, maybe even use.

The Developer.com article I wrote last year, 10 Experimental PHP Projects Pushing the Envelope, was originally intended to be little more than an homage to nontraditional PHP efforts that stretched beyond standard Web application development tools such as PHP-GTK and phpList. [...] Not only did this article turn out to be very entertaining to write, but it wound up being one of the most popular articles I wrote for Developer.com in 2010.

Some of the projects in this post include PHP for Android, PL/PHP, Objective-PHP and Apns-PHP (using Apple's Push Notification Services).
