[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 MongoDB\Driver\Manager("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\"?>\r\n<model>\r\n\t  <fields>\r\n\t  <field label=\"标题\" name=\"title\" type=\"string\" widget=\"title\" required=\"1\" maxLength=\"60\" minLength=\"1\"   esAnalyzed=\"analyzed\" esAddNoAnalyzed=\"yes\" >\r\n\t\t<widgetParams>\r\n\t\t\t<param name=\"marks\" value=\"5,13.5,40\"\/>\r\n\t\t<\/widgetParams>\r\n\t\t<validation>\r\n\t\t\t<rule type=\"maxZhLength\" value=\"40\" msgZh=\"标题长度不能超过40个汉字长度\" \/>\r\n\t\t<\/validation>\r\n\t<\/field>\r\n\t\t  <\/fields>\r\n  <layout>\r\n\t<fieldset name=\"basic\" legend=\"基本信息\">\r\n\t\t<field name=\"title\" width=\"12\"\/>\r\n\t<\/fieldset>\t\r\n  <\/layout>\r\n<\/model>";

        $params['isTest']='0';

        $params['desc']='shihan添加';

        $params['auditFeedback']='';

        $params['status']='1';

       $params['audited']='1';

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

        $bulk = new MongoDB\Driver\BulkWrite();

        $sets= ['$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 = [];

        $options = [];

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

        $query = new MongoDB\Driver\Query($filter, $options);

        $cursor = $this->mongoManger->executeQuery($this->dbName.$collect, $query);

        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 = [];

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

        $query = new MongoDB\Driver\Query($filter, $options);

        $cursor = $this->mongoManger->executeQuery($this->dbName.$collect, $query);

        foreach ($cursor as $document) {

            var_dump($document);

        }

    }

}

$docModel=new DocModel();

$docModel->getModel(true);
