Alternate to array_column()

Question

I have used array_column() in a project, and after uploading I found out that only PHP 5.5 or above support this function, and I think the hosting I use don\'t

Answer 1

You can also use the alternative code of array_column(), it's simple just paste below line and replace your variable.

Code:

array_map(function($element){return $element['last_name'];}, $a);
