<?php
array(
    'test_1' => array(
        'msg_1' => 'this is the first desc',
        'msg_2' => 'this is the second desc',
    ),
    'test_2' => 'this is the third desc',
    'test_3' => array(
        'msg_1' => array(
            'foo_1' => 'this is the fourth desc',
        ),
        'msg_2' => 'this is the fifth desc',
    ),
    'this is the sixth desc',
);

Desired result

What we want the output is
