[PHP-DEV] Access to syntax tree?

[Jeremy]

Is there any way to access the parse tree of a PHP file from within PHP?
I'm trying to write a code-checking utility to find namespace-related 
problems in code and alert me to them.  Specifically:

namespace foo\bar;

function foobar()
{
        try
        {
                ...
        }
        catch(Exception $e)
        {
                //nothing will be caught
                //I forgot to qualify
                //code silently fails
        }
}

I didn't want to put a whole lot of work into this, so I'm trying to 
avoid having to write in C/flex/ANTLR/etc.  There's a bit of 
grease-monkey internals stuff in PHP so I thought I would check.

Thanks,
Jeremy
