MONGODBDRIVERMANAGER(3) 1 MONGODBDRIVERMANAGER(3)
The MongoDBDriverManager class
INTRODUCTION
The MongoDBDriverManager is the main entry point to the extension. It is responsible for maintaining connections to MongoDB (be it
standalone server, replica set, or sharded cluster).
No connection to MongoDB is made upon instantiating the Manager. This means the MongoDBDriverManager can always be constructed, even
though one or more MongoDB servers are down.
Any write or query can throw connection exceptions as connections are created lazily. A MongoDB server may also become unavailable during
the life time of the script. It is therefore important that all actions on the Manager to be wrapped in try/catch statements.

teOptions], [MongoDBWriteConcern $writeConcern])

EXAMPLES
Example #1
MongoDBDriverManager.__construct(3) basic example
var_dump(3)ing a MongoDBDriverManager will print out various details about the manager that are otherwise not normally expopsed.
This can be useful to debug how the driver views your MongoDB setup, and which options are used.
<?php
$manager = new MongoDBDriverManager("mongodb://localhost:27017");
var_dump($manager);
?>
The above example will output something similar to:
object(MongoDBDriverManager)#1(3) {
["request_id"]=>
int(1714636915)
["uri"]=>
string(25) "mongodb://localhost:27017"
["cluster"]=>
array(13) {
["mode"]=>
string(6) "direct"
["state"]=>
string(4) "born"
["request_id"]=>
int(0)
["sockettimeoutms"]=>
int(300000)
["last_reconnect"]=>
int(0)
["uri"]=>
string(25) "mongodb://localhost:27017"
