run code in 300+ PHP versions simultaneously
<?php $string = "hello my friend"; $newString = ''; foreach(str_split($string) as $char) { $asciiCode = ord($char); // 97 - a // 122 - z if ($asciiCode >= 97 && $asciiCode < 122) { $char += 1; } if (in_array($char, ['a', 'e', 'y', 'u', 'i', 'o'])) { // not 32, because we already added 1 before $char -= 33; } $newString .= chr($char); }

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).
