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.

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

}

?>
