run code in 300+ PHP versions simultaneously
<?php class A {} class D { protected function test1($class_name) { echo $class_name, "\n"; return 'BLAH'; } public function test($class_name) { return new $class_name($this->test1($class_name)); } } $D = new D; var_dump($D->test('A')); var_dump($D->test('D'));

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).
