In a note from Sebastian Bergmann's weblog today, he talks about the porting of some frameworks and tools from Java to PHP.

A couple of Java bloggers (Steve, Stefan) have discovered Phing, which is Apache Ant ported to PHP. I myself have ported JUnit from Java to PHP (PHPUnit) and know of ports of JavaDoc (phpDocumentor), JDBC (Creole), and Propel).

What I would like to see are ports of Apache Maven (or a Maven-like application based on DOAP) and DamageControl. Do you know of other frameworks or tools that have been ported from Java to PHP? Post them in a comment to this entry!

For more info and more of the ideas people have suggested, check out the comments (such as Popoon, Rails, etc)...
