PHP 用 ZipArchive 打包指定文件到zip供用户下载
Ubuntu需安装zlib
sudo apt-get install ruby sudo apt-get install zlib1g zlib1g.dev
Windows需开启php_zip.dll
如果在 "...\php\ext\" 没有这个文件,可以到网上下载一个
然后修改 "...\php\php.ini" ,找到 "extension=php_zip.dll" 去掉 ";",如果没有这行就加上。
$filename = "xxxx.zip"; ob_end_clean(); $zip = new ZipArchive(); $zip->open($filename, ZipArchive::OVERWRITE); while (xxxx) { if(strlen($row->team_upload) != 0) { $sitelen = strlen($row->team_upload); $attachfile = xxxx//写绝对径,建议用PHP环境变量 $attachfile=iconv("UTF-8","GBK",$attachfile); //转码,打包中文文档 $zip->addFile( $attachfile , basename($attachfile)); //把文件放入zip } } $zip->close();//关闭 header('Content-Description: File Transfer'); Header("content-type:application/x-zip-compressed"); header('Content-Disposition: attachment; filename='.basename($filename)); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($filename)); ob_clean(); //清空但不关闭输出缓存 flush(); @readfile($filename); @unlink($filename);//删除打包的临时zip文件。文件会在用户下载完成后被删除
