Hi Jeremy,
The parser file needs to be updated to reflect additions in PHP 5.3, but
http://pear.php.net/PHP_Parser provides an example of a parser in which
you could actually check for every class reference at parse-time,
ignoring everything else.
It's built using the tokenizer extension as a lexer, and a port of lemon
to PHP for the parser (zend_language_parser.y is also ported into lemon
format)
