run code in 300+ PHP versions simultaneously
<?php //$var1 = "1"; $var2 = "2"; function foo() { global $var1, $var2; var_dump($var1 ?? $var2); } 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).
