<? $mongo=new mongoclient("mongodb://xhomuser:passworddb!@test.server.com:27017/test-db?readpreference=primary"); echo "<pre>";  $db = $mongo->selectdb("test-db");  $collection = $db->selectcollection("messages");  $cursor = $collection->find(); foreach ($cursor $document) {     echo '"_id": '.$document["_id"]."<br />";     echo '"accountnumber": '.$document["accountnumber"]."<br />";     echo '"status": '.$document["status"]."<br />"; }   ?>
