run code in 300+ PHP versions simultaneously
<?php var_dump(" 2" == " 2"); var_dump(" 2 " == " 2 "); var_dump(" 2 " == 2); var_dump(" 2 " == " 2");

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).
