The Mongo class

(No version information available, might only be in SVN)

Introdução

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.

For those who are concerned on parsing JSON associative arrays from queries, this class could be useful. You just have to extend it and call parent constructor and it gets the job done.
It automatically initializes all your object attributes getting values from the array.

<?php

    #doc
    #    classname:    MongoClass
    #    scope:        PUBLIC

        #    internal variables
        protected $id;
       
        #    Constructor
        function __construct ($attList = array())
        {
            $reflection = new ReflectionObject($this);

            foreach ($attList as $attName => $attValue)
            {
                $attObj = $reflection->getProperty($attName);
                $attObj->setAccessible(true);
                $attObj->setValue($this, $attValue);
            }
        }

        class A extends MongoClass {
                private $name;
                private $value;

                public function __construct($attList) {
                        parent::__construct($attList);

        $attList = array(
                "name" => "Beer",
                "value" => "Delicious",
                "weight" => 15.2
        ); //This is your JSON object associative aray

        $a = new A($attList);

Here is a simple connection function :)

<?php
function MongoConnect($username, $password, $database, $host) {
    $con = new Mongo("mongodb://{$username}:{$password}@{$host}"); // Connect to Mongo Server
    $db = $con->selectDB($database); // Connect to Database
}
?>
