打印HABTM结果

Question

我正在使用cake 2.0，我试图在我的视图中打印出以下内容。即一个用户的朋友，我无法理解如何将其打印出来。即时通讯使用HABTM关系，它似乎正在发挥作用。

控制器发送一个名为＆＃34; $ users＆＃34;的变量。视图，但我似乎无法正确打印出来（我不太熟悉Php阵列＆＃39;）

任何人都可以帮助我（调试$ users）

Answer 1

没有任何格式化，循环将是：

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

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