Last night, in order to This matter of packaging and downloading has caused a lot of trouble. There are several problems, the first one is the problem of starting PHP_ZIP.dll. In other words, just remove the ";" sign in front of extend_dir in PHP.INI. Just restart IIS or apache.

$zip->open($filename.".zip", ZipArchive::OVERWRITE); //$data 就是从数据库里面读出的数字
foreach( $data as $val){
   $attachfile = "E:\bysj\bysj".$val['fileaddr'].$val['filename']; //写硬路径，但建议用PHP环境变量
   $attachfile=iconv("UTF-8","GBK",$attachfile); //转码，是打包中文文档的关键
   $zip->addFile( $attachfile , basename($attachfile)); //压栈
}
$zip->close();//关闭
header("Content-type:text/html;charset=utf-8");//设置页面编号
header("Cache-Control: public");
header("Content-Description: File Transfer");
header('Content-disposition: attachment; filename='.basename($filename)); //文件名
header("Content-Type: application/zip"); //zip格式的
