run code in 300+ PHP versions simultaneously
<?php $a = array(); $a[123] = array(); $a[123][] = array('a' => 'abc', 'b' => 'def'); $a[123][] = array('a' => '123', 'b' => '456'); foreach($a as $key => $val){ print $key; print $val; }

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).
