symfony2 php访问另一个实体的对象

I know its very lame question to ask. I have One Entity ContentSelector and another is Content in Content Selector I have a property Content where I have Id. I am trying to access the Content propety but always getting error. This is what I am trying to do.

$cs = $pages->getContentSelector();

it returns:

[

{
    "id": ​22,
    "title": "my Title",
    "content": "11021,10930,10874,10766,10954,10705,10948,10934,11048,11049,10831"
}

]

now I want to get the content property like $cs->content getting error like:

"Notice: Undefined property: Doctrine\\ORM\\PersistentCollection::$content"

tried with getContent(); getting error that the method doesnt exist. but in ContentSelector the method actually exists.

how can I easily get the content ids?

我知道这是一个非常蹩脚的问题。 我有一个实体ContentSelector，另一个是内容选择器中的内容我有一个属性内容，我有Id。 我正在尝试访问Content propety但总是收到错误。 这就是我想要做的。 

  $ cs = $ pages-＆gt; getContentSelector（）; 
   
 
 <  p>它返回： 
 
 
  [
 
 {
“id”：22，
“title”：“my title”，
“content”  ：“11021,10930,10874,10766,10954,10705,10948,10934,11048,11049,10831”
} 
 
] 
   
 
 
现在 我想得到像 $ cs-＆gt; content 这样的内容属性，如： 
 
 
 “注意：未定义的属性：Doctrine \\ ORM \  \ PersistentCollection :: $ content“
   
 
 
尝试使用getContent（）; 得到该方法不存在的错误。 但在ContentSelector中，该方法实际存在。 
 
 
如何轻松获取内容ID？

    The getContentSelector() method return an ArrayCollection so you need to access to an element of the collection before call a method of the contained object. As example, you can access to the first element as follow:

    $collection = $pages->getContentSelector();
$cs = $collection->first();

    Then you can try access to the objet element (from the dump seems a json object?)

    Hope this help
