php链接mongo数据库

[半支烟z]

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

这么写完之后报错

$dsn="mongodb://localhost:27017/admin:admin/aaa"; $m=new MongoClient($dsn); 没有报错了

Deprecated: main(): The Mongo class is deprecated, please use the MongoClient class 反对：main()：Mongo类是过时的，请使用mongoclient类

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

错误提示
mongo contact:

你的下图是什么？mongo 管理器？ 你看看他是怎么写的

下图是一个mongoweb的管理地址，我看了好多写法，好像链接都是那么写的，不清楚为什么我的出错了，所以贴出来数据库的结构，我想这样能表述的更清晰一点
