Implode on a nested array

Question

I want to implode every "a_skill" in this array into a string. Usually I would do implode(", ", $my_array); but this is nested. Is there an easy way to handle this?

Array
(
    [0] => Array
        (
            [email] => don.pinkus@gmail.com
            [a_skill] => test
        )

    [1] => Array
        (
            [email] => don.pinkus@gmail.com
            [a_skill] => testerrrr
        )

)

From PHP's array docs, array_keys looks promising but I can't get it to work.

Why dont you just run a loop and grab the value into an array that way? — Sterling Archer, Aug 27 '13 at 01:44
possible, but with PHP's slough of array functions figured there was an easy one — Don P, Aug 27 '13 at 01:46

If you are using PHP 5.5 then you can use array_column like follows:

$a_skill_array = array_column($my_array, 'a_skill');
echo implode(', ', $a_skill_array);
