The MongoDB class

Introduction

Instances of this class are used to interact with a database. To get a database:

<?php
$m = new Mongo(); // connect
$db = $m->selectDB("example");
?>

Database names can use almost any character in the ASCII range. However, they cannot contain " ", "." or be the empty string.

A few unusual, but valid, database names: "null", "[x,y]", "3", "\"", "/".

Unlike collection names, database names may contain "$".
