ThinkPHP框架下如何用PHP自带的ZipArchive类打包压缩文件

public function downloadzip(){    $catid = $this->request->param(‘catid/d‘, 0);    $id = $this->request->param(‘id/d‘, 0);    $category = getCategory($catid);    if (empty($category)) {        $this->error(‘该栏目不存在！‘);    }        $modelid = $category[‘modelid‘];        $fieldList = $this->Cms_Model->getFieldList($modelid, $id);

    $attatchs=$fieldList[‘uploadmaterial‘][‘value‘];

    $attatchsarray=explode(‘,‘,$attatchs);    $zip=new \ZipArchive();    $downpath=[];    $timefils=date("Ymd",time());    if(!file_exists(‘uploads/zip/‘.$timefils)){        mkdir (‘uploads/zip/‘.$timefils,0777,true);    }

    $zipName =‘uploads/zip/‘.$timefils.‘/download‘.$id.‘.zip‘;

    if($zip->open($zipName,\ZipArchive::OVERWRITE | \ZipArchive::CREATE)==TRUE){        foreach($attatchsarray as $key=>$value){            $downpath=dirname(ROOT_PATH).get_file_path($value);            $downpathname=get_file_name($value); //改文件一定得为本地地址不可以为域名地址                $zip->addFile($downpath, basename($downpathname));  //basename($downpathname)这个是压缩包里面的文件名称

        }    }    $zip->close();

    if(!file_exists($zipName)){        $this->error(‘文件创建失败‘);    }    header(‘Content-Type: application/zip‘);    header(‘Content-disposition: attachment; filename=‘.$zipName);    header(‘Content-Length: ‘ . filesize($zipName));//文件大小    readfile($zipName);}
