run code in 300+ PHP versions simultaneously
<?php $array =[]; $array['info']['user']['name'] = 'Jack'; $array['info']['user']['age'] = '15'; $foo = ['location' => 'bar', 'something' => 'foo', 'bar' => 'some']; array_merge($array['info'], $foo); print_r($array); //expected result /* [info] => [ 'location' => 'bar', 'something' => 'foo', ' 'bar' => 'some' 'user' => [ 'name' => Jack 'age' => 15 ] ] */

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).
