run code in 300+ PHP versions simultaneously
<?php $compare = array( '0 == "str"', '0 == "1"', '0 == ""', ); foreach ($compare as $code) { echo '(' . $code . ') = '; var_dump(eval('return (' . $code . ');')); }

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).
