Question

我的FbUserEntity ArrayCollection多PageEntity。

 $fbUser->getPageLikes(); 

 //will give back an array of many PageEntity classes:
  object(stdClass)[1410]
     public '__CLASS__' => string 'MyBundle\Entity\PageEntity' (length=41)
     public 'id' => int 877
     public 'fbId' => string '8245623462' (length=10)
     public 'name' => string 'NBA' (length=3)

我有一系列facebookId，如：

array (size=2)
  0 => string '8245623462' (length=10)
  1 => string '1239653462' (length=10)

我想从$ PageEntity获取fbUser个实体，其中fbId的{{1}}可以在另一个数组中找到（实际上我只需要任何数组项都可以在PageEntity集合中找到。检查示例我做了以下代码：

PageEntity

执行时我收到错误消息：

/* @var FbUserEntity $fbUser */
  $uLikes = $fbUser->getPageLikes();
  $criteria = Criteria::create()
    ->where(Criteria::expr()->in("fbId", $qLikes))
    ->setMaxResults(1);

  $preferred = $uLikes->matching($criteria);

有趣的是An exception occurred while executing 'SELECT te.id AS id, te.fbId AS fbId, te.name AS name FROM Page te JOIN Page_Like t ON t.page = te.id WHERE t.user = ? AND te.fbId = ?' with params [22, ["8245623462","1239653462"]]: Notice: Array to string conversion期望参数2是一个数组，它是。另一件事是内部查询不应该使用Criteria::expr()->in()而不是AND te.fbId IN (?)吗？

Doctrine Criteria（）匹配DBALException
