code

foreach($cats $key=>$val){     $cats2[$val['lable']] = $mycollection->aggregate( array(                                 array('$match' => array('user_id' => $user_id )),                                 array('$unwind' =>"\$data"),                                 array('$match' => array('data.category'=> $val['category'])),                                 array('$project' => array('name'=> "\$data.name", 'id'=>"\$data.id")),                                 array('$group' => array('_id'=>'$id', 'name'=> array('$first' =>'$name'))),                                 array('$limit' => 12)                                     )); }
