run code in 300+ PHP versions simultaneously
<?php $a=" "; echo "enter the number of rows"; $b=fgets(STDIN); $num=1; for($a=1;$a>$b;$a++) { echo "$a"; exit(0); }

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).
