插入多陣列數據庫環路

Question

我有以下陣列

Array 
(
    [user_id] => Array 
    (
     [0] => 1 
     [1] => 1 
     [2] => 1 
     [3] => 1 
    ) 

    [menu_id] => Array 
    (
     [0] => 1 
     [1] => 1 
     [2] => 1 
     [3] => 1 
    ) 

[submenu_id] => Array 
    (
     [0] => 1 
     [1] => 2 
     [2] => 3 
     [3] => 4 
    ) 

) 

我的MySQL數據庫是象下面這樣：

user_id | menu_id | submenu_id 
     |   | 

我想上面插入陣列到我的數據庫象下面這樣：

user_id | menu_id | submenu_id 
    1 | 1  | 1 
    1 | 1  | 2 
    1 | 1  | 3 
    1 | 1  | 4 

如何插入上面的數據？謝謝。

因爲您在每個陣列上都有相同的索引，所以您希望從第一個陣列（user_id）和第一個陣列（menu_id）等獲得第一個值，並將其添加到mysql中的一行。

你需要這樣的事情：

foreach($data['user_id'] as $key => $user_id){ 
    //You have $user_id 
    $menu_id = $data['menu_id'][$key]; 
    $submenu_id = $data['submenu_id'][$key]; 
    //All of this 3 variables you need now to insert to mysql. Try it and let me know WITH code if something is not working like this. 
}
