run code in 300+ PHP versions simultaneously
<?php $values = array( 0, 1, '1', 1.00, 1.01, 2.33, 3.445 -3.45 ); foreach($values as $value) { $regexp = '/^[-]?[0-9]+\.[0-9][0-9]?$/'; preg_match($regexp, $value, $matches); var_dump($matches); }

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).
