php連結mongo資料庫

$conn = new Mongo("mongodb://admin:admin@localhost:27017/local"); ///這個就是第11行

這麼寫完之後報錯

( ! ) Deprecated: main(): The Mongo class is deprecated, please use the MongoClient class in D:\bzyweb\test2\conn.php on line 11

回複討論(解決方案)

Deprecated: main(): The Mongo class is deprecated, please use the MongoClient class
反對：main()：Mongo類是過時的，請使用mongoclient類

echo "mongo contact:
";
//$DB = new PDO("mongodb:host=localhost;port=27017;dbname=aaa","admin","admin");
$conn = new MongoClient("mongodb://admin:admin@localhost2:27017/local");
?>

錯誤提示
mongo contact:

( ! ) Fatal error: Uncaught exception 'MongoConnectionException' with message 'MongoClient::__construct(): ' in D:\bzyweb\test2\conn.php on line 4
( ! ) MongoConnectionException: MongoClient::__construct(): in D:\bzyweb\test2\conn.php on line 4

你的是什嗎？mongo 管理器？
你看看他是怎麼寫的

是一個mongoweb的管理地址，我看了好多寫法，好像連結都是那麼寫的，不清楚為什麼我的出錯了，所以貼出來資料庫的結構，我想這樣能表述的更清晰一點

$dsn="mongodb://localhost:27017/admin:admin/aaa";
$m=new MongoClient($dsn);
沒有報錯了
