MongoDB::__construct
(PECL mongo >=0.9.0)
MongoDB::__construct — Creates a new database
Описание
This method is not meant to be called directly. The preferred way to create an instance of MongoDB is through MongoClient::__get() or MongoClient::selectDB().
If you're ignoring the previous paragraph and want to call it directly you can do so:
<?php
$m = new MongoClient();
$db = new MongoDB($m, 'mydbname');
?>
But don't. Isn't this much nicer:
<?php
$m = new MongoClient();
$db = $m->mydbname;
// or, if the name contains weird characters:
$db = $m->selectDB('my,db:name');
?>
Возвращаемые значения
Returns the database.
Ошибки
Throws default exception if the database name is invalid.

To use DICE (Dependency Injection Container) you'll need to use this format
// $Mongo = new \MongoClient( arrConnectionOptions );
// $Mdb = new \MongoDB( $Mongo, 'dbName' );
$dice->create( '\Mongo' );
$dice->create( '\Mdb' );
and not this one
$Mdb = $Mongo->dbName;
