mongodb - 无法在 mongodb 中保存 PHP 对象

Question

保存对象时出现“不允许使用零长度键”的 fatal error 。

是因为 __construct() 的存在吗？

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，您希望 mongo 如何读取您的私有(private)类变量。
