run code in 300+ PHP versions simultaneously
<?php function bla () { function blubb () { echo "It works"; } return blubb; } // This doesn't work: //bla()(); //This works: const x = bla(); x();

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).
