无法在mongodb中保存PHP对象

Question

获取'零长度键不被允许'保存对象时出现致命错误。

是否由于__construct（）的存在？

我相信PHP对象在save（）方法中是允许的。

class Address{ 
    private $name; 
    private $company; 
    private $zip; 

    public function __construct($name,$company,$zip){ 
     $this->name = $name; 
     $this->company = $company; 
     $this->zip = $zip; 
    } 
} 

$newAddress = new Address("james","google",678); 

print_r($newAddress); 
// Address Object ([name:Address:private] => james [company:Address:private] => 
// google [zip:Address:private] => 678) 

$addresses->save($newAddress);  

Fatal error: Uncaught exception 'MongoException' with message 'zero-length keys are not allowed, did you use $ with double quotes?' in /var/www/html/index.php:105 Stack trace: #0 /var/www/html/index.php(105): MongoCollection->save(Object(Address)) #1 {main} thrown in /var/www/html/index.php on line 105

嗯，你怎么能指望MONGO读你私人类变量。
