Work has been done on rewriting the PHP parser to Lemon in a specific branch: http://svn.php.net/viewvc/php/php-src/branches/LEMON/ Right now, the Lemon parser is not actually faster than the current bison parser, so I would suggest not to put this in PHP 5.4 until it performs at least as well as the current parser. Are there any possibilities for optimisation so far? cheers, Derick -- http://derickrethans.nl | http://xdebug.org Like Xdebug?
