1.封装MongoDB类

<?phpclass MongoDB{    private $database;    private $mongo;    function __construct()     {        $this->mongo  = new MongoClient("mongodb://user:password@server_address:port/admin");        $this->database = $this->mongo->selectDB("data");    }{        return $this->database->selectCollection($collection);    }    //获取所有的集合名    function getCollections()     {        return $this->database->getCollectionNames();    }    //选数据库    function selectDB($db)    {        $this->database = $this->mongo->selectDB($db);    }}

2.简单调用，insert数据。

class DemoController extends CI_Controller{    function __construct() {        parent::__construct();        //CI中加载类        $this->load->library('mongo_lib', '', 'mongodb');    }    //插入一条数据    function create()    {        $data = array('name'=>'mike','email'=>'abc@163.com);        //选择库，shell：user demo_db        $this->mongodb->selectDB('demo_db');        //选择集合,db.demo_col.insert();        $rebateCollection = $this->mongodb->getCollection('demo_collection');        $res = $rebateCollection->insert($data);    }}
