run code in 300+ PHP versions simultaneously
<?php $conf = array(); $test = array( array( 'conf1' => '1' ), array( 'conf2' => '2' ), array( 'conf3' => '3' ), ); foreach ($test as $item) { var_dump($item); $config = array_merge($conf); } var_dump($conf);

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).
