run code in 300+ PHP versions simultaneously
<?php $m = 'foo'; $GLOBALS = []; var_dump($m);//foo unset($GLOBALS['m']); var_dump($m);//notice (undefined) //$GLOBALS = array_diff_key($GLOBALS, ['m'=>null]);

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).
