        string(2) "Test1"
      }

use the following:

$return = array_merge_recursive($array, ...);

in your case:

$return = array_merge_recursive($array[0], $array[1]);

but I am guessing you'll want a more dynamic solution, I will draft that up now.

$return = call_user_func_array('array_merge_recursive', $array);

@user3042036 please check out the latter 2 snippets as they can both be used in your situation, the final one being dynamically adapted to any amount of array elements.
