orm - Doctrine 2 ArrayCollection filter method

Question

Can I filter out results from an arrayCollection in Doctrine 2 while using lazy loading? For example,

// users = ArrayCollection with User entities containing an "active" property
$customer->users->filter('active' => TRUE)->first()

It's unclear for me how the filter method is actually used.

Answer 1

Doctrine now has Criteria which offers a single API for filtering collections with SQL and in PHP, depending on the context.

Update

This will achieve the result in the accepted answer, without getting everything from the database.

use DoctrineCommonCollectionsCriteria;

/**
 * @ORMEntity
 */
class Member {
  // ...
  public function getCommentsFiltered($ids) {
    $criteria = Criteria::create()->where(Criteria::expr()->in("id", $ids));

    return $this->getComments()->matching($criteria); 
  }
}
