run code in 300+ PHP versions simultaneously
<?php $re = "/^[a-zA-Z ,.\p{Han}]+$/u"; $tests = array( 'Mr Smith', 'Mr. Smith', 'Mr. 123 Smith', '姓名' ); foreach ($tests as $test) { if (preg_match($re, $test) !== 1) { echo $test . ' failed' . PHP_EOL; } }

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).
