run code in 300+ PHP versions simultaneously
<?php class A { public function a() { echo "a\n"; } } class B extends A { public function b() { echo "b\n"; } } $b = new B; $b->a(); $b->b();

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).
