Question

ID我有一個用戶表如下

TABLE USERS 
user_id  user_name  user_rooms 
1   PAUL   serialized and base64_encoded data (1, 2, 4, 5, 6, 7, 8, 9, 10) 
2   JOHNL   serialized and base64_encoded data (1, 2, 3) 
3   MARK   serialized and base64_encoded data (3) 

我需要創建從該表數組USER_ID至極訪問的房間，在此示例中到室溫3：

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

查詢（即將切換至的mysqli）爲：

$result = mysql_query("SELECT user_id, user_rooms FROM table_users"); 
$rooms = Array(); 

while ($row = mysql_fetch_assoc($result)) { 
     $user_room[] = unserialize(base64_decode($row['user_rooms'])); 
} 

$rooms返回房間數組，我想獲得與user_id數組

任何幫助嗎？

Answer 1

您可以使用此代碼：

$data=array(); 
while ($row = mysql_fetch_assoc($result)) { 
     $data[$row['user_id']] = $row['user_rooms']; 
} 

訪問，你可以像這樣訪問：

echo "$data[index]";
