I had this crazy idea like some years ago.. I wasn't expecting it be factible, and there's still some semantic problems with this approach

Anyways, the whole idea was to take some java source, generate an AST, and output it back as syntactically correct PHP.

why? 50% fun + 50% exploration

So I have this really basic compiler, which can roughly output its own code; what's still missing?

    - static vs instance detection (-> vs ::)
    - class' properties
    - method visibility
    - enums
    - inner types
    - annonymous classes
    - dealing with method overriding

There's a huge gap in the semantic area (eg: String.format vs sprintf) that is way out of scope for this hack.
