run code in 300+ PHP versions simultaneously
<?php $str = " one! two:\tthree; 'four' "; print_r(str_word_count($str, 1)); print_r(preg_split("/\s+/",trim($str))); print_r(array_filter(explode(' ', implode(' ', array_map('trim', explode("\n", $str))))));

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).
