PHP变化的变量

Question

我已经开始建立这个类的，我想注册一个用户：为什么它返回Success

$user = User::register($_POST['username'],$_POST['email'],$_POST['password'],$captcha,$agree); 
if(empty($user->errors)) { 
    echo 'Success'; 
} else { 
    echo 'Failed'; 
} 

：

<?php 
class User { 
    protected $_id; 
    protected $_name; 
    protected $_email; 
    protected $_password; 
    public $isLogged = false; 
    public $errors = array(); 

    public function __construct() { 

    } 
    public static function register($username,$email,$password,$captcha,$agree) { 
     $user = new self; 
     array_push($user->errors,'Error!'); 
    } 
} 

我这样称呼它？我做过array_push！

Answer 1

class User { 

    // ... 

    public static function register($username,$email,$password,$captcha,$agree) { 
     $user = new self; 
     array_push($user->errors,'Error!'); 
     return $user; 
    } 
} 

你忘了从register()返回$user对象。
