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. CLASS SYNOPSIS

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" ["requires_auth"]=> int(0) ["nodes"]=> array(...) ["max_bson_size"]=> int(16777216) ["max_msg_size"]=> int(50331648) ["sec_latency_ms"]=> int(15) ["peers"]=> array(0) { } ["replSet"]=> NULL } } PHP Documentation Group MONGODBDRIVERMANAGER(3)

MONGOCLIENT(3) 1 MONGOCLIENT(3) The MongoClient class INTRODUCTION
A connection manager for PHP and MongoDB. This class is used to create and manage connections. A typical use is: Example #1 MongoClient basic usage <?php $m = new MongoClient(); // connect $db = $m->foo; // get the database named "foo" ?> See MongoClient.__construct(3) and the section on connecting for more information about creating connections.

MONGOCLIENT CONSTANTS
o MongoClient::VERSION - PHP driver version. May be suffixed with "dev", "+" or "-" if it is in-between versions. o MongoClient::DEFAULT_HOST - "localhost" - Host to connect to if no host is given. o MongoClient::DEFAULT_PORT - 27017 - Port to connect to if no port is given. o MongoClient::RP_PRIMARY - "primary" -Read preference for the primary replica set member. o MongoClient::RP_PRIMARY_PREFERRED - "primaryPreferred" -Read preference for preferring the primary replica set member. o MongoClient::RP_SECONDARY - "secondary" -Read preference for a secondary replica set member. o MongoClient::RP_SECONDARY_PREFERRED - "secondaryPreferred" -Read preference for preferring a secondary replica set member. o MongoClient::RP_NEAREST - "nearest" -Read preference for the nearest replica set member. FIELDS
o $connected - This property will be set to TRUE if we have a open connection to the database, FALSE otherwise. If the connection is to a replica set, this property will only be TRUE if the driver has a connection to a node matching the current read preference. This property does not take authentication into account. This property is deprecated since version 1.5.0. o $status - This property is no longer used and will be set to NULL In driver versions 1.1.x and earlier, this may be set to a string value (e.g. "recycled", "new") when persistent connections are used. This property is deprecated since version 1.5.0. SEE ALSO
