CakePHP 3：即使未从数据库中提取数据，也会返回true

I'm working in CakePHP 3.2. There is a table user_addresses from which I'm trying to fetch all records of an user

public function myFun()
{
    $this->loadModel('UserAddresses');
    $user_id = $this->Auth->user('id');
    $userAddresses = $this->UserAddresses->find('all', [
       'conditions' => [
           'user_id' => $user_id
       ]
    ]);
    if (empty($userAddresses)) {
       echo 'Hello';               // for testing only
    } else {
       echo 'World';
    }
}

To check it, I added myFun to controller's beforeFilter

$this->Auth->allow(['myFun']);

and this prints World instead of Hello since there is no data retrieved from database because if user is not logged in then $user_id must be empty.

我在CakePHP 3.2中工作。 有一个表 user_addresses ，我正试图从中获取用户的所有记录 

  public function myFun（）
 {
 $  this-＆gt; loadModel（'UserAddresses'）; 
 $ user_id = $ this-＆gt; Auth-＆gt; user（'id'）; 
 $ userAddresses = $ this-＆gt; UserAddresses-＆gt; find（'all  '，[
'conditions'=＆gt; [
'user_id'=＆gt; $ user_id 
] 
]）; 
 if（empty（$ userAddresses））{
 echo'Hello';  //仅用于测试
} else {
 echo'World'; 
} 
} 
   
 
 
要检查它，我添加了 myFun  到控制器的 beforeFilter   
 
 
  $ this-＆gt; Auth-＆gt; allow（['myFun']）; 
   
 
 
打印世界而不是 Hello ，因为没有从数据库中检索到数据，因为如果用户没有登录则  $ user_id 必须为空。

    First of all check if $user_id is available then and then call find() method.

    public function myFun()
{
    $this->loadModel('UserAddresses');
    $user_id = $this->Auth->user('id');
    if(empty($user_id)){
        echo "Not able to access this method";
        die();
    }
    $userAddresses = $this->UserAddresses->find('all', [
       'conditions' => [
           'user_id' => $user_id
       ]
    ]);
    if (empty($userAddresses)) {
       echo 'Hello';               // for testing only
    } else {
       echo 'World';
    }
}
