我目前的代码是：

// Here we choose the folder which will be used.

            // Choose a name for the archive.
            $zipFileName = 'myzip.zip';

            // Create "MyCoolName.zip" file in public directory of project.
            $zip = new ZipArchive;

            if ( $zip->open( public_path() . '/' . $zipFileName, ZipArchive::CREATE ) === true )
            {
                // Copy all the files from the folder and place them in the archive.
                foreach ( glob( $dirName . '/*' ) as $fileName )
                {
                    $file = basename( $fileName );
                    $zip->addFile( $fileName, $file );
                }

                $zip->close();

                $headers = array(
                    'Content-Type' => 'application/octet-stream',
                );

                // Download .zip file.
                return Response::download( public_path() . '/' . $zipFileName, $zipFileName, $headers );

Creating A File Download Response

创建文件下载响应

return Response::download($pathToFile);

return Response::download($pathToFile, $name, $headers);

Maybe you should avoid to repeat the second

也许你应该避免重复第二个

$zipFileName

在你的最后一行代码中。

You can “create a zip of multiple files and download in PHP” below way.

您可以通过以下方式“创建多个文件的 zip 文件并在 PHP 中下载”。

To create a zip of multiple files and download with PHP it has some below features:

要创建多个文件的 zip 文件并使用 PHP 下载，它具有以下一些功能：

• It will create a zip file by using ZipArchive Library.
• Before creating a file it will check file exist or not.
• If a file exists then it will remove the file.
• If file not exists then it will create
• a zip file with multiple passed for it.

• When the zip is ready it will be auto download.

  //get path of files
  $path = base_path();
  $file_path = $path."/../uploads/advatise/";
  //getting data from database
  $row = $this->getRow($ids);
  //if data exist
  if($row) {
      //multiple images in single attrubute
      $images=$row->advertise_image;
      $images=explode(",",$images);
      //creating zip object
      $zip = new ZipArchive();
      //creating file name
      $DelFilePath="images".$row->id.".zip";
      //if file exists then to delete it
      if(file_exists($file_path.$DelFilePath)) {
          unlink ($file_path.$DelFilePath);
      }
      //if not exist then to create zip file
      if ($zip->open($file_path.$DelFilePath, ZIPARCHIVE::CREATE) 
  != TRUE) {
          die ("Could not open archive");
      }
      //loop on the images/file to add in zip
      foreach ($images as $key => $image) {
          $zip->addFile($file_path.$image,$image);
      }
      // close and save archive
      $zip->close();
      //opening zip and saving directly on client machine
      header("Location:".Request::root()."/uploads/advatise/".$DelFilePath);
  }
  exit;
  

• 它将使用 ZipArchive 库创建一个 zip 文件。
• 在创建文件之前，它将检查文件是否存在。
• 如果文件存在，那么它将删除该文件。
• 如果文件不存在，那么它将创建
• 一个带有多个传递的 zip 文件。

• 当 zip 准备好后，它将自动下载。

  //get path of files
  $path = base_path();
  $file_path = $path."/../uploads/advatise/";
  //getting data from database
  $row = $this->getRow($ids);
  //if data exist
  if($row) {
      //multiple images in single attrubute
      $images=$row->advertise_image;
      $images=explode(",",$images);
      //creating zip object
      $zip = new ZipArchive();
      //creating file name
      $DelFilePath="images".$row->id.".zip";
      //if file exists then to delete it
      if(file_exists($file_path.$DelFilePath)) {
          unlink ($file_path.$DelFilePath);
      }
      //if not exist then to create zip file
      if ($zip->open($file_path.$DelFilePath, ZIPARCHIVE::CREATE) 
  != TRUE) {
          die ("Could not open archive");
      }
      //loop on the images/file to add in zip
      foreach ($images as $key => $image) {
          $zip->addFile($file_path.$image,$image);
      }
      // close and save archive
      $zip->close();
      //opening zip and saving directly on client machine
      header("Location:".Request::root()."/uploads/advatise/".$DelFilePath);
  }
  exit;
