我使用方法

得到了一个涉及symfony2中几个对象的变量

\Doctrine\Common\Util\Debug::dump($article);

我有

array(1) { [0]=> object(stdClass)#267 (19) { ["__CLASS__"]=> string(30) "obbex\AdsBundle\Entity\AdsList" ["id"]=> int(33) ["username"]=> string(7) "aviator" ["email"]=> string(17) "aviator@gmail.com" ["telephone"]=> string(4) "5161" 
["displayPhone"]=> string(3) "non" ["title"]=> string(14) "aviator jacket" ["description"]=> string(14) "aviator jacket" ["country"]=> string(6) "France" 
["region"]=> string(13) "Ile de France" ["department"]=> string(5) "Paris" ["address"]=> string(15) "15, rue Dantzig" ["city"]=> string(5) "Paris" ["zipCode"]=> 
string(5) "75015" ["statusPro"]=> string(3) "oui" ["creationtime"]=> string(8) "DateTime" ["updatetime"]=> string(8) "DateTime" ["publication"]=> bool(true) ["photos"]=> string(8) "Array(1)" } }

带

\Doctrine\Common\Util\Debug::dump($article[0]);

我可以访问第一个数组插槽[0]

object(stdClass)#267 (19) { ["__CLASS__"]=> string(30) "obbex\AdsBundle\Entity\AdsList" ["id"]=> int(33) ["username"]=> string(7) "aviator" ["email"]=> string(17) 
"aviator@gmail.com" ["telephone"]=> string(4) "5161" ["displayPhone"]=> string(3) "non" ["title"]=> string(14) "aviator jacket" ["description"]=> string(14) "aviator jacket" ["country"]=> string(6) "France" ["region"]=> string(13) "Ile de France" 
["department"]=> string(5) "Paris" ["address"]=> string(15) "15, rue Dantzig" ["city"]=> string(5) "Paris" ["zipCode"]=> string(5) "75015" ["statusPro"]=> string(3) "oui" ["creationtime"]=> object(stdClass)#365 (3) { ["__CLASS__"]=> string(8) "DateTime" ["date"]=> string(25) "2014-06-06T21:54:00+02:00" ["timezone"]=> string(12) "Europe/Paris" }
 ["updatetime"]=> object(stdClass)#366 (3) { ["__CLASS__"]=> string(8) "DateTime" ["date"]=> string(25) "-001-11-30T00:00:00+00:09" ["timezone"]=> string(12) "Europe/Paris" } ["publication"]=> bool(true) ["photos"]=> array(1) { [0]=> string(29) "obbex\AdsBundle\Entity\Photos" } }

如何访问第一个对象（stdClass）'obbex \ AdsBundle \ Entity \ AdsList' 我试过了

\Doctrine\Common\Util\Debug::dump($article[0]->{'obbex\AdsBundle\Entity\AdsList'});

和

\Doctrine\Common\Util\Debug::dump($article[0]->'obbex\AdsBundle\Entity\AdsList');

没有成功。

我认为您的问题在于如何（取消）序列化您的对象。我假设你想要一个obbex\AdsBundle\Entity\AdsList - 对象而不是stdClass - 对象。

你可以做的是，检查__CLASS__，然后从构造函数中传递stdClass - 对象的对象创建一个新对象来传递数据：

$rawData = (array) $article[0]; // Convert stdClass to array for easier handling
$className = $rawData['__CLASS__'];
// TODO Maybe check, that class name is valid
$object = new $className($rawData);

您的类只需要在构造函数中填充数组中的属性：

namespace obbex\AdsBundle\Entity;

class AdsList
{
    protected $username;
    protected $email;
    ...

    public function __construct(array $data = array())
    {
        if (empty($data)) {
            return;
        }

        // TODO Check only valid properties/values are used
         $this->username = $data['username'];
         ...
         // OR
         foreach ($data as $name => $value) {
             $this->{$name} = $value;
         }
    }
}

您可以通过确保检索实际对象而不是stdClass来节省一些麻烦，例如确保serialize()和deserialize(string $serialized)已实施/使用。
