run code in 300+ PHP versions simultaneously
<?php $i = imagecreatefrompng("http://in-the-attic.com/img/posts/teaching-my-5-year-old-daughter-to-code/script_before.png"); for ($x=0;$x<imagesx($i);$x++) { for ($y=0;$y<imagesy($i);$y++) { $rgb = imagecolorat($i,$x,$y); $r = ($rgb >> 16) & 0xFF; $g = ($rgb >> & 0xFF; $b = $rgb & 0xFF; $rTotal += $r; $gTotal += $g; $bTotal += $b; $total++; } } echo round($rTotal/$total); echo round($gTotal/$total); echo round($bTotal/$total);

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).
