run code in 300+ PHP versions simultaneously
<?php /* $a = '0xf'; $b = '15'; $c = 15; var_dump('Vars', $a, $b, $c); var_dump('EQ', $a == $b, $a == $c, $b == $c); */ test('pie', function($a){return $a}); function test($label, $lambda){ echo $label; foreach(['0xf', '15', 15] AS $k=>$v) { $r = $labda($v); var_export($r); } echo "\n"; }

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).
