run code in 300+ PHP versions simultaneously
<?php $text = '<p>www.test.com</p>'; echo 'pcre.backtrack_limit: ' . ini_get('pcre.backtrack_limit') . PHP_EOL; $chunks = preg_split('/(<.+?>)/is', $text, -1, PREG_SPLIT_DELIM_CAPTURE); echo 'error: ' . preg_last_error() . PHP_EOL; is_array($chunks) ? print_r($chunks) : var_dump($chunks); ini_set('pcre.backtrack_limit', 1); echo 'pcre.backtrack_limit: ' . ini_get('pcre.backtrack_limit') .

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).
