run code in 300+ PHP versions simultaneously
<?php $count = 1024 * 128; $loops = 10000; for ($i = 0; $i < $count + 1; $i++) { $a["k$i"] = TRUE; } for ($i = 0; $i < $loops; $i++) { unset($a["k$i"]); $j = $i + $count; $a["k$j"] = TRUE; }

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).
