// Get gridfs object
$ prefix = 'pic';
$ collection = $ db-> getGridFS ($ prefix);
// Upload picture
if (isset ($ _ FILES ['upfile'] )) {
$ id = $ collection-> storeUpload ('upfile');
$ id = strval ($ id);

$ prefix = 'pic';
$ collection = $ db-> getGridFS ($ prefix);
$ id = $ _GET ['id'];
$ object = $ collection-> findOne (array ('_ id' => new MongoId ($ id)));
header (' Content-type: image / jpg ');
echo $ object-> getBytes ();
?>
