Question

我想使用PHP解析mongo文档并在TWIG中显示该文档的元素。
但我现在被卡住了。

这是我的文档的一部分：

{"_id":
{"$id":"555f91d9fd2897e433000029"},
"users":[{"id":1735706894,
"id_str":"1735706894","name":"Funny Teen Quotes",
"screen_name":"D_Funny_Teens"},
{"id":1239321974,
"id_str":"1239321974",
"name":"Teen Quotes",
"screen_name":"SayingsOnTeens"} ...

这是我的函数PHP：

   public function testAction()
{
    $m = $this->container->get('doctrine_mongodb.odm.default_connection');
    $db = $m->selectDatabase('test');
    $collection = $db->createCollection('tweets');
    $followcollection = $db->createCollection('followers');
    $follow  = $followcollection->findOne();
    $k = 0;
    foreach ($follow->users as $follower) {
        $returns[$k] = array(
            $follower->id,
            $follower->id_str
        );
        $k = $k+1;
    }

    $return = json_encode($return);
    return $this->render('ChartsBundle:Charts:test.html.twig', 
    array('returns'=> $returns
    )); }

我的模板树枝：

{% for item in return %}
 <li>{{ returns.id }}</li>
 <li>{{ returns.id_str }}</li>
 {% endfor %}

我收到此错误

 Notice: Trying to get property of non-object

Answer 1

请尝试：

(...)


$follow  = (object) $followcollection->findOne();
$k = 0;
foreach ($follow->users as $arrFollower) {
    $follower = (object)$arrFollower;
    $returns[$k] = (object)array(
        $follower->id,
        $follower->id_str
    );
    $k = $k+1;
}


(...)

我会使用DoctrineMongoDBBundle。这样您就可以使用常规PHP对象。
