Remove empty array values

This snippet will remove all the empty values from an array and returns the cleared array. If the input is not an array, it will return false

Example of use:

print_r(clear_empty_values($array));

function clear_empty_values($arr)
{
	if (!is_array($arr)) return false;
	$new = array();
	while(list($k, $v) = each($arr))
	{
		$v = trim($v);
		if ($v != '' || !empty($v)) $new[$k] = $v;
	}

	return $new;
}
