run code in 300+ PHP versions simultaneously
<?php function g($x=0){return$x?'g'.$x:function($y)use($x){return$x.g($y);};} echo g('al'); /* echo g('al') , PHP_EOL; echo g()('al') , PHP_EOL; echo g()()('al') , PHP_EOL; echo g()()()('al') , 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).
