php - How can I print all values in group option? -

-

i couldn't find. i've read , done of these: http://docs.mongodb.org/manual/reference/aggregation/ , these: http://php.net/manual/en/mongocollection.aggregate.php

but couldn't make happen. i'm trying learn, complicated. mongodb complicated.

this code:

$hg = $collection_iddaa->aggregate(array(        array('$project'=>         array(             'lig_adi'=>1,             'ulke_adi'=>1,             'ulke_kisa'=>1,             'hometeam'=>1,             'awayteam'=>1,             'homegol'=>1,             'awaygol'=>1,             'baslangic'=>1,             'status'=>1,             'ptime'=>1         )     ),     array( '$group' => array(         '_id' => array('lig_adi'=>'$lig_adi', 'ulke_adi'=>'$ulke_adi'),             "ulke_kisa" => array('$addtoset' => '$ulke_kisa'),             "hometeam" => array('$addtoset' => '$hometeam'),             "awayteam" => array('$addtoset' => '$awayteam'),             'homegol'=>array('$addtoset' => '$homegol'),             'awaygol'=>array('$addtoset' => '$awaygol'),             'baslangic'=>array('$addtoset' => '$baslangic'),             'status'=>array('$addtoset' => '$status'),             'ptime'=>array('$addtoset' => '$ptime')             ))     ));

when use $addtoset option, returning unique value , doesn't show repeats. want show values, not unques. should do? how can show values after use group option.

i want show "ulke_kisa" "hometeam" "awayteam" "homegol" bla bla bla, after using group.
