How does this work for connections to replication sets?
Does the connection string become:
"mongodb://user:password@server1:27017,server2:27017,server3:27017"
认证
如果 MongoDB 服务器启动时使用了 --auth 或
--keyFile 参数，你就必须在进行任何操作前进行认证。
你可以在连接时进行认证。方法是在链接字符串中指定用户名密码，或者在
MongoClient::__construct() 构造函数中指定
"username" 和 "password"。
Example #1 针对“admin”数据库的认证
<?php
// Specifying the username and password in the connection URI (preferred)
$m = new MongoClient("mongodb://${username}:${password}@localhost");
// Specifying the username and password via the options array (alternative)
$m = new MongoClient("mongodb://localhost", array("username" => $username, "password" => $password));
?>
默认状态下，驱动会针对 admin 数据库进行认证。认证也可以对其他数据库进行。方法是在连接字符串中指定数据库名，或者
MongoClient::__construct() 构造函数中指定
"db"。
Example #2 针对一般数据库的认证
<?php
// Specifying the authentication database in the connection URI (preferred)
$m = new MongoClient("mongodb://${username}:${password}@localhost/myDatabase");
// Specifying the authentication database via the options array (alternative)
$m = new MongoClient("mongodb://${username}:${password}@localhost", array("db" => "myDatabase"));
?>
如果链接中断，驱动会重新尝试链接并会自动重新认证。

For connecting to a replica set with authentication it is possible to use a connection string like the following (substitute the port numbers, replica set name and DB with your own)
$m = new MongoClient("mongodb://${username}:${password}@localhost:27037,mongodb://${username}:${password}@localhost:27038",
array("replicaSet" => "test"_replica, "db" => "mytestdb"));
The second member string "mongodb://${username}:${password}@localhost:27038" does not need the username and password - however, if the connection to the first member fails I have not tested to see if the username and password persist to the second member.
