run code in 300+ PHP versions simultaneously
<?php class Base{ function hello(){ echo "hello "; $this->world(); } function world(){ echo "world"; } } class Derived extends Base{ function world(){ echo "World!!!!!"; } } $x = new Derived(); $x->hello();

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).
