无法在mongodb中保存PHP对象

Question

保存对象时不允许'零长度键'出现致命错误。

是否存在__construct（）？

我相信save（）方法允许使用PHP对象。

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);    

  

致命错误：不允许使用带有“零长度密钥”消息的未捕获异常“MongoException”，您是否使用带双引号的$？在/var/www/html/index.php:105堆栈跟踪：＃0 /var/www/html/index.php(105）：MongoCollection-＆gt;保存（对象（地址））＃1 {main}抛出第105行的/var/www/html/index.php

Answer 1

嗯，您如何期待mongo阅读您的私有类变量。
