run code in 300+ PHP versions simultaneously
<?php $a = [[00, 01, 02, 03], [10, 11, 12, 13], [20, 21, 22, 14], [30, 31, 32, 34]]; $b = 2; echo $a[$b][$b++], PHP_EOL; $b = 2; echo $a[$b=$b][$b++], PHP_EOL;

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).
