run code in 300+ PHP versions simultaneously
<?php preg_match("%^(\w+)$%", "",$matches); print_r($matches); echo "\n"; preg_match("/(\w*)/", "",$matches); print_r($matches);

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).
