PHP Abstract Syntax Tree

Hi,

Is it planned to modify the PHP compiler in order to create an abstract
syntax tree rather than generating directly the opcode ?
It will allow to perform tasks like Type inference, optimization etc...

Best regards,

William

I already wrote an program which converts PHP source code to AST but I don't
understand why the native PHP compiler doesn't use this approach.

Hi William,
if you are interested in converting PHP source code to AST, you may find
the
Phalanger system useful.
See http://php-compiler.net.
