run code in 300+ PHP versions simultaneously
<?php <?php $tests = array( "42", 1337, "1e4", "not numeric", array(), 9.1, '234ffffdsf' ); foreach ($tests as $element) { if (is_numeric($element)) { echo "'{$element}' - число", PHP_EOL; } else { echo "'{$element}' - НЕ число", PHP_EOL; } }

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).
