title: Faster way of doing this?
body: <p>I have the following code, but it runs the foreach loop one at a time. Is there a way of making them all run at once?</p>
  
  <pre><code>foreach($json['orders']['cnr_output_ship_to_header'] as $header)
  {
      $orders_array[] = $header;
      $guests_array[] = $header['guests']['cnr_output_guest_detail'];
      $items_array[] = $header['items']['cnr_output_item_detail'];
  }   
  
  foreach($guests_array as $guests)
  {
      pdo_insert('cnr_output_guest_detail', (array)$guests);
  }
  foreach($items_array as $items)
  {
      pdo_insert('cnr_output_item_detail', (array)$items);
  }
  foreach($orders_array as $orders)
  {
      pdo_insert('cnr_output_ship_to_header', (array)$orders);
  }
  </code></pre>
