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.

The Boris Guéry answer’s at this post, may help you:
Doctrine 2, query inside entities

$idsToFilter = array(1,2,3,4);

$member->getComments()->filter(
    function($entry) use ($idsToFilter) {
       return in_array($entry->getId(), $idsToFilter);
    }
);
