run code in 300+ PHP versions simultaneously
<?php if (preg_match('/^(?P<base>[^[]+)(?P<extra>(\[.*)|$)/', 'foo[bar][baz]', $m)) { $segments = array($m['base']); while (preg_match('/^\[(?P<segment>.*?)\](?P<extra>.*)$/', $m['extra'], $m)) { echo $m['segment']."\n"; } }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
