run code in 300+ PHP versions simultaneously
<?php $foo = "0wz"; $foo++; var_dump($foo, hexdec($foo)); $foo++; var_dump($foo); echo "PHP goes to $foo";

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).
