更快的方法呢？

Question

我有下面的代碼，但它一次運行一個foreach循環。有沒有一種方法可以讓它們一次運行？

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); 
} 

Answer 1

爲什麼不這樣：

foreach($json['orders']['cnr_output_ship_to_header'] as $header) { 
    //$orders_array[] = $header; 
    pdo_insert('cnr_output_ship_to_header', (array)$header); 
    //$guests_array[] = $header['guests']['cnr_output_guest_detail']; 
    pdo_insert('cnr_output_guest_detail', (array)$header['guests']['cnr_output_guest_detail']); 
    //$items_array[] = $header['items']['cnr_output_item_detail']; 
    pdo_insert('cnr_output_item_detail', (array)$header['items']['cnr_output_item_detail']); 

} 

Answer 2

這應該只是罰款

foreach ($json['orders']['cnr_output_ship_to_header'] as $header) { 
    pdo_insert('cnr_output_guest_detail', (array) $header['guests']['cnr_output_guest_detail']); 
    pdo_insert('cnr_output_item_detail', (array) $header['items']['cnr_output_item_detail']); 
    pdo_insert('cnr_output_ship_to_header', (array) $header); 
}
