印刷HABTM結果

Question

即時通訊使用蛋糕2.0和即時通訊嘗試打印出下列在我看來。即用戶的朋友，我不知道如何打印出來。即時通訊使用HABTM關係，它似乎正在工作。

控制器發送一個名爲「$用戶」變量的看法，但我似乎無法得到它打印出正確（IM與PHP數組的不是太familar）

誰能幫助我（$用戶的調試）

Array 
(
    [0] => Array 
     (
      [User] => Array 
       (
        [id] => 104 
        [username] => admin 

       ) 

      [Friend] => Array 
       (
        [0] => Array 
         (
          [id] => 107 
          [username] => carskitchens 

          [Retailerrelationship] => Array

           ) 

         )

沒有任何格式，循環將是：

foreach($users as $user) 
{ 
    echo $user['User']['name']; 

    foreach($user['Friend'] as $friend) 
    { 
    echo $friend['username']; 
    } 
}
