使用mongodb聚合，

use MongoDB;
$this->connection = new MongoDB\Client("mongodb://localhost:27017");
private $dbname = 'database';
private $db;
private $collection;
$this->db = $this->connection->{$this->dbname};
$this->collection = $this->db->collection;


$date = Date("Y-m-d H:i:s", strtotime("-24 hours"));
$pipeline = array(
['$match' =>[
    ['created' =>['$gt'=> $this->timedate->setDate($date)]]
]                
]);
$query = $this->collection->aggregate($pipeline);
return $query->toArray();
