run code in 300+ PHP versions simultaneously
<?php echo "lorem Ipsum dolor sit Amet"; $array1=array("abc","def"); $array2=array("ghi","jkl"); $a1=array("red","green"); $a2=array("blue","yellow"); print_r(array_merge($a1,$a2)); $array3=array_merge($array1,$array2); echo $array3; ?>

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).
