run code in 300+ PHP versions simultaneously
<?php class Foo { private $orig; public function bar() { $this->orig = clone $this; } } $foo = new Foo; for ($i = 0; $i < 20; $i++) { $foo->bar(); echo (memory_get_peak_usage(true) / 1024 / 1024) . "\n"; }

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).
