run code in 300+ PHP versions simultaneously
<?php class Foo { public function __construct($foo, $bar, $foo) {} } $r = new ReflectionClass('Foo'); $params = $r->getConstructor()->getParameters(); var_export($params[2]->name); echo "\n\n"; echo json_encode($params[2]->name[0]); if ($params[2]->name[0] == "\u0000") echo '!!';

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).
