array_walk is an option, but here's another option if you want to try something a bit more coded by yourself, solving this problem recursively

This will flatten any n-max level array into a single array that contains all the values of all the sub arrays (including the initial array itself)

<?php
$array = array(
1 => array(1, 2, 3, 4 => array(
1, 2, 3, 4
)),
4, 5);
function recurse_values($array) {
    if (is_array($array)) {
        $output_array = array();
        foreach ($array as $key=>$val) {
            $primitive_output = recurse_values($val);
            if (is_array($primitive_output)) {
                $output_array = array_merge($output_array, $primitive_output);
            }
            else {
                array_push($output_array, $primitive_output);
            }
        }
        return $output_array;
    }
    else {
        return $array;
    }
}
print_r(recurse_values($array));
?>

If you need unique values, at the end you can add a array_unique to do this.

You can use array_walk

$array = array(...); //your values here
function output($item, $key) {
     echo $key . ' =>' . $item;
}
array_walk($array, 'output');

Are you asking how you can "flatten" this multi-dimensional array into a one dimension? Possible solutions to similar problems... How to Flatten a Multidimensional Array?
