TP5.1批量下载文件到ZIP并保存原有的文件名称

TP5.1批量下载无需外部插件进行批量下载zip

//获取所有下载文件ID
			$idList = explode(",",$info[idList]);

            //批量下载遍历文件地址
            $files = [];
            for($i = 0;$i<count($idList);$i++)
            {
                $contract = Contract::get($idList[$i]);
                $downSrc = Env::get(root_path).public.$contract[contractfile];
                array_push($files,$downSrc);
            }
			//TP自带的类
            $zip = new ipArchive;
            //压缩文件名
            $filename = Date(Y-m-d).合同批量下载.zip;
            //新建zip压缩包
            $zip->open($filename,IPARCHIVE::OVERWRITE | IPARCHIVE::CREATE);
            //循环压缩文件
            foreach($files as $key => $value){
                $fileStr = trim(strrchr($value,/),/);//获取文件路径
                $str = substr($fileStr,32);//获取后缀
                //查询文件名称（若之前保存文件为源文件名保存可跳过该步骤）
                $fileStr_b = Contract::where(contractfile,like,%.$fileStr)->find()[contractname];
                $zip->addFile($value,basename($fileStr_b.$str));
            }
            //打包zip
            $zip->close();
