The Mongo class

简介

A connection between PHP and MongoDB.

This class is used to create and manage connections. A typical use is:

<?php

$m = new Mongo(); // connect
$db = $m->foo; // get the database named "foo"

?>

See Mongo::__construct() and the section on connecting for more information about creating connections.
