run code in 300+ PHP versions simultaneously
<?php foreach(array( '.aaf', '..dafeafw', '..', '.' ) as $test) { var_dump(substr($test, 0, 1) === '.'); }

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).
