run code in 300+ PHP versions simultaneously
<?php $a = 5; $b = &$a; echo $a++.$a++; //echo ++$a.$b++; //echo $b; //echo $a++ . ++$a; //echo ++$a . $a++;

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).
