One of the problems I have with that project is that none of the functions are namespaced or sandboxed (i.e. all global); but then again, it is emulating PHP, so there you go :)

Indeed, been using php.js for quite a while here now. Will give this other one a shot later on though, see how they compare to one another.

I don't think they are comparable. The one linked by toni[1] takes PHP code and compiles it for running in Javascript; the one linked by kaolinite[2] is a translation of some PHP methods into pure Javascript.
