run code in 300+ PHP versions simultaneously
<?php echo "0 to string comparison: " . PHP_EOL; var_dump(array( '0 == "one"' => (0 == "one"), '0 == "null"' => (0 == "null"), '0 == "1"' => (0 == "1"), '0 == "0"' => (0 == "0"), '0 == ""' => (0 == ""), ));

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).
