檢查下面的代碼，它用來MongoDB的用PHP連接。

$m = new MongoClient(); 
$db = $m->yourDB; 

$collection = $db->yourCollecton; 

$sdate = '2016-01-01'; 
$sdate = '2016-01-31'; 

$pipeline = array(
    array(
     '$match'=>array('date'=>array('$gte'=>$sdate,'$lte'=>$edate))  
    ), 
    array(
     '$group' => array(
      '_id' => array(null), 
      'first_field' => array('$field'), 
     ) 
    ) 
); 

$cursor = $collection->aggregate($pipeline); 
$row = $cursor['result'][0];
