Как вывести трехмерный массив?

$main_array = array('movie' => $new,);
    
    foreach($main_array as $brand => $massiv)
    {
    foreach($massiv  as  $inner_key => $value)
    {
    if (is_array($value)) {
       foreach($value as $key => $val) {
        echo "[$brand][$inner_key][$key] = $val
    ";
       }
    }
    echo "[$brand][$inner_key] = $value
    ";
  
    }
    }
