通过多维数组值获取数组部分

Question

I have the following array:

Array
(
    [fall] => Array
        (
            [info] => Array
                (
                    [Name] => Test
                    [Description] => Test description
                    [Slug] => tester
                )

            [images] => Array
                (
                    [0] => fall_1.jpg
                    [1] => fall_2.jpg
                    [2] => fall_3.jpg
                    [3] => fall_4.jpg
                )

        )

    [spring] => Array
        (
            [images] => Array
                (
                    [0] => spring_1.jpg
                    [1] => spring_2.jpg
                    [2] => spring_3.jpg
                    [3] => spring_4.jpg
                    [4] => spring_5.jpg
                )

        )

)

What I'm looking to do is get the fall array if both info exists and Slug is equal to tester. I researched and saw this question/answer but mine is dependent on a sub-array being available -- would it be the same idea?

As an example, if tester was the only param given, I'd want the fall array to be returned.

You could easily just do

if (isset($array['fall']['info']['Slug']) && $array['fall']['info']['Slug'] == 'tester') {
    return $array['fall'];
}
