PHP封装的简单连接MongoDB类示例

PHP封装的简单连接MongoDB类。具体如下：

1. 封装MongoDB类

  <?php  class 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);    }  }
