Roundup Of PHP Web Application Frameworks

Here is a list of web application frameworks that are written in PHP.  Some of those were inspired by Ruby On Rails, or seek to imitate it. Others are frameworks with varying goals. All are PHP based.

• CakePHP has been covered before on this web site.
• And so is PHPOnTrax.
• More recently, I wrote about WASP. 
• Prado.  
• Symfony.
