无法在mongodb中保存PHP对象 [英] unable to save PHP objects in mongodb

问题描述

在保存对象时获取不允许使用零长度密钥"致命错误.

Getting 'zero-length keys are not allowed' FATAL error while saving object.

是因为存在__construct()吗?

Is it due to presence of __construct() ?

我相信save()方法中允许使用PHP对象.

I believe PHP object is allowed in save() method.

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:未捕获的异常"MongoException"，消息为不允许使用零长度密钥，您是否在$中使用了双引号?"在/var/www/html/index.php:105中的堆栈跟踪:#0/var/www/html/index.php(105):MongoCollection-> save(Object(Address))#1 {main}抛出于/var/www/html/index.php，第105行

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
