废话不多说，直接上代码
//这里需要注意该目录是否存在，并且有创建的权限 $zipname = 'path/test.zip' //这是要打包的文件地址数组 $files = array("mypath/test1.txt","mypath/test2.pdf"); $zip = new ZipArchive(); $res = $zip->open($zipname, ZipArchive::CREATE); if ($res === TRUE) { foreach ($files as $file) { //这里直接用原文件的名字进行打包，也可以直接命名，需要注意如果文件名字一样会导致后面文件覆盖前面的文件，所以建议重新命名 $new_filename = substr($file, strrpos($file, 'https://www.jb51.net/') + 1); $zip->addFile($file, $new_filename); } } //关闭文件 $zip->close();
//这里是下载zip文件 header("Content-Type: application/zip"); header("Content-Transfer-Encoding: Binary"); header("Content-Length: " . filesize($zipname)); header("Content-Disposition: attachment; filename=\"" . basename($zipname) . "\""); readfile($zipname); exit;
附：这里再为大家提供一个zip压缩类：
