run code in 300+ PHP versions simultaneously
<?php namespace X; $iterator = new \RegexIterator( new \ArrayIterator( ['A.phpt', 'B.phpt', 'C.phpt'] ) , '/\.phpt$/' , \RegexIterator::MATCH ) ; foreach ($iterator as $foo) { var_dump($foo); pcre_study('/\.phpt$/', '', ''); } echo "Done", PHP_EOL;

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).
