run code in 300+ PHP versions simultaneously
<?php ob_start(); function level(){ function level2(){ echo 'Text that won\'t get displayed.'; } } level(); echo "\n"; var_dump(ob_get_level()); ?>

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).
