MongoDB::__construct — Creates a new database

### Description

public MongoDB::__construct ( MongoClient `$conn` , string `$name` )

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');
?>`

### Parameters

MongoClient `conn`

  Database connection.

`name`

  Database name.

### Return Values

Returns the database.

### Errors/Exceptions

Throws default exception if the database name is invalid.
