[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']="\r\n\r\n\t  \r\n\t  \r\n\t\t\r\n\t\t\t\r\n\t\t<\/widgetParams>\r\n\t\t\r\n\t\t\t\r\n\t\t<\/validation>\r\n\t<\/field>\r\n\t\t  <\/fields>\r\n  \r\n\t
\r\n\t\t\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);
