run code in 300+ PHP versions simultaneously
<?php $arr = array('a' => 1); $var = 11; $var = @$arr['b']; echo (empty($var) ? 'true' : 'false');

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).
