run code in 300+ PHP versions simultaneously
<?php namespace one; //use one as three; class test2{ public function result(){ echo '1'; }} namespace one\two\three; class test{ public function result(){ echo '201a'; }} namespace one\two; class test{ public function result(){ echo '0'; }} $test = new three\test(); $test->result();

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).
