run code in 300+ PHP versions simultaneously
<?php class A{ public function __construct(){ echo "A::__construct()\n"; } public function somePrint(){ echo "fuck off!"; } public function someCycle($n=100){ $s=''; $arr=array(); $num=0; for($i=0;$i<$n;$i++){ $s.=$i; $num+=$i; array_push($arr, $i); } echo "END cycle\n"; } } $a = new A(); $a->somePrint(); $b = new A(); $b->someCycle();

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).
