run code in 300+ PHP versions simultaneously
<?php function foo(&$x) { try { $x = 'trying'; return $x; } finally { $x = 'finally'; } } $bar = 'main'; echo foo($bar) . $bar . PHP_EOL; $bar = foo($bar); echo $bar . $bar . PHP_EOL; function baz() { try { return 'trying'; } finally { return 'finally'; } } echo baz() . 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).
