[PHP]新版的mongodb扩展安装和使用

旧版的mongo扩展已经不推荐使用了，在php7以上一般是安装和使用新版的mongodb扩展

ubuntu下

apt-get install php-mongodb

例如下面的代码进行了查询和插入集合操作

<?php
class DocModel{
    public $mongoManger=null;
    public $dbName='coms';
    public function __construct(){
        // 连接到mongodb
        $this->mongoManger = new MongoDBDriverManager("mongodb://127.0.0.1:27017");
    }
    //添加文档模型
    public function addModel($isDraft=false){
        $params=[];
        $params['modelID']='basic_news';
        $params['name']='基础新闻';
        $params['parentID']='root';
        $params['modelXML']="<?xml version="1.0" encoding="utf-8"?>

	  <fields>
	  <field label="标题" name="title" type="string" widget="title" required="1" maxLength="60" minLength="1"   esAnalyzed="analyzed" esAddNoAnalyzed="yes" >

		<validation>

  <layout>
	<fieldset name="basic" legend="基本信息">
		<field name="title" width="12"/>
	</fieldset>	
  </layout>

        $params['isTest']='0';
        $params['desc']='shihan添加';

       $collect=$isDraft ? '.modelDraft':'model';

        $bulk = new MongoDBDriverBulkWrite();
        $sets= ['$set' => $params];
        $bulk->update(['modelID' => $params['modelID']],$sets, ['multi' => false, 'upsert' => true]);
        $this->mongoManger->executeBulkWrite($this->dbName.$collect, $bulk);
    }
    //文档模型列表
    public function listModel($isDraft=false){
        $filter = [];

        foreach ($cursor as $document) {
            var_dump($document);
        }
    }
    //获取文档模型详情
    public function getModel($isDraft=false){
        $params['modelID']='basic_news';
        $filter = ['modelID'=>$params['modelID']];
        $options = [];
