How to “flatten” a multi-dimensional array to simple one in PHP?

This is a one line, SUPER easy to use:

$result = array();
array_walk_recursive($original_array,function($v) use (&$result){ $result[] = $v; });

It is very easy to understand, inside the anonymous function/closure. $v is the value of your $original_array.
