Authentication
If MongoDB is started with the --auth or
--keyFile options, you must authenticate before you can do
any operations with the driver. You may authenticate a connection by
specifying the username and password in either the connection URI or the
"username" and "password" options for
MongoClient::__construct().
Example #1 Authenticating against the "admin" database
<?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" => $password));?>
By default, the driver will authenticate against the admin
database. You may authenticate against a different database by specifying it
in either the connection URI or the "db" option for
MongoClient::__construct().
Example #2 Authenticating against normal databases
<?php// Specifying the authentication database in the connection URI (preferred)$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"));?>
If your connection is dropped, the driver will automatically attempt to reconnect and reauthenticate you.
