run code in 300+ PHP versions simultaneously
<?php $file = 'example.txt'; $newfile = 'example.txt.bak'; if (!copy($file, $newfile)) { echo "failed to copy $file...\n"; }

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).
