The MongoDB\Driver\Manager class

(mongodb >=1.0.0)

Introducción

The MongoDB\Driver\Manager 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 MongoDB\Driver\Manager 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.

Sinopsis de la Clase

final MongoDB\Driver\Manager {
/* Métodos */
final public __construct ( string $uri [, array $options [, array $driverOptions ]] )
final public MongoDB\Driver\WriteResult executeBulkWrite ( string $namespace , MongoDB\Driver\BulkWrite $bulk [, MongoDB\Driver\WriteConcern $writeConcern ] )
final public MongoDB\Driver\Cursor executeCommand ( string $db , MongoDB\Driver\Command $command [, MongoDB\Driver\ReadPreference $readPreference ] )
final public MongoDB\Driver\Cursor executeQuery ( string $namespace , MongoDB\Driver\Query $query [, MongoDB\Driver\ReadPreference $readPreference ] )
final public array getServers ( void )
final public MongoDB\Driver\Server selectServer ( MongoDB\Driver\ReadPreference $readPreference )
}

Ejemplos

Ejemplo #1 MongoDB\Driver\Manager::__construct() basic example

var_dump()ing a MongoDB\Driver\Manager will print out various details about the manager that are otherwise not normally exposed. This can be useful to debug how the driver views your MongoDB setup, and which options are used.

<?php

$manager = new MongoDB\Driver\Manager("mongodb://localhost:27017");
var_dump($manager);

?>

El resultado del ejemplo sería algo similar a:

object(MongoDB\Driver\Manager)#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
  }
}
