run code in 300+ PHP versions simultaneously
<?php $c = '€'; echo bin2hex($c) . "\n"; echo bin2hex(iconv('UTF-8', 'CP850//TRANSLIT', $c)) . "\n";

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).
