Check this out: parse_url.php: <?php for ($i = 0; $i < 50000; $i++) { $fullurl = "http://www.example.com:80/blah/bing?foo=bar&gazonk=true"; $url = parse_url($fullurl); } ?> $ time php parse_url.php real 1m41.777s user 1m35.770s sys 0m0.200s preg_match.php: <?php for ($i = 0; $i < 50000; $i++) { $fullurl = "http://www.example.com:80/blah/bing?foo=bar&gazonk=true"; preg_match('!^(([^:/?#]+):)?(//([^/:?#]*)(:(\d+))?)?([^?#]*)(\\?([^#]*))?(#(.*))?!', $fullurl, $matches); list(,,$url['scheme'],,$url['host'],,$url['port'],$url['path'],,$url['query']) = $matches; } ?> $ time php preg_match.php real 0m2.950s user 0m2.940s sys 0m0.000s ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16545&edit=1
