run code in 300+ PHP versions simultaneously
<?php foreach (UConverter::getAvailable() as $encoding) { printf('%s: %s' . PHP_EOL, $encoding, implode(', ', UConverter::getAliases($encoding))); }

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).
