You can use array_walk_recursive() for that coupled with a closure:

$res = array(); // initialize result

// apply closure to all items in $data
array_walk_recursive($data, function($item) use (&$res) {
    // flatten the array
    $res[] = $item;
});

print_r($res); // print one-dimensional array
