MongoDB使用测试

根据官网提供的使用案例进行学习，下面是我的测试代码

<?php 
class Mongo_Driver{

	public function insertOne(){

		$user = array(
				'first_name' => 'MongoDB',
				'last_name' => 'Fan',
				'tags' => array('developer','user')
			);
		// Configuration
		$dbhost = 'localhost';
		$dbname = 'test';

		// Connect to test database
		$m = new Mongo("mongodb://$dbhost");
		$db = $m->$dbname;

		// Get the users collection
		$c_users = $db->users;

		// Insert this new document into the users collection
		$c_users->save($user);
	}

	public function selectOne(){
		// Configuration
		$dbhost = 'localhost';
		$dbname = 'test';

		// Connect to test database
		$m = new Mongo("mongodb://$dbhost");
		$db = $m->$dbname;

		// Get the users collection
		$c_users = $db->users;

		// Find the user with first_name 'MongoDB' and last_name 'Fan'
		$user = array(
			'first_name' => 'MongoDB',
			'last_name' => 'Fan'
		);

		$user = $c_users->findOne($user);
		var_dump($user);
	}

	public function selectByLimit(){
