run code in 300+ PHP versions simultaneously
<?php $time = microtime(true); for ($i = 0; $i < 10000; $i++) { $array = []; $str = '|' . implode('|', array_keys($_SERVER)); do { if (false !== $pos = strpos($str, '|SCRIPT_')) { if (false !== $pos2 = strpos($str, '|', $pos + 1)) { $len = $pos2 - $pos - 1; } else { $len = null; } $array[] = substr($str, $pos + 1, $len); $str = $pos2 !== false ? substr($str, $pos2) : ''; } } while ($pos !== false && $str); } var_dump(count($_SERVER), $array, microtime(true) - $time);

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).
