run code in 300+ PHP versions simultaneously
<?php class test { private $_cpt ; public function compt() { $_cpt ++; return $_cpt; } } $insta1 = new test(); // Un $insta2 = new test(); // 2 echo 'cpt : '. $insta1->compt();

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).
