php compiler for making statnd alone application

Hi all,

I am looking for some open source free php compiler that can compile my whole web site so that it can run on a stand alone system.

Basically i want to write small appliaction so that users should be able to make changes into their web site(located on their local/desktop system) using my browser based applicaiton. Means a small browser based CMS that can change files on their local system and than they can upload the changed files to their required live server....

Regards,
Nazim
