NAME
	flatten_array - flatten out an array

SYNOPSIS
	mixed *flatten_array(mixed *arr)


DESCRIPTION
	The returned array will have a depth of 1. That means none of the
	elements will contain an array. Arrays found within an element
	will be inserted into the final array replacing the element. This
	function works recursively on nested arrays.
