在php中创建zip和下载在Mozilla浏览器中不起作用

Question

我试图创建一个zip文件，并通过使用ZipArchive库的PHP脚本下载它。

$post['files']这个变量包含Amazon S3上托管的图像的URL，所以首先我将它们下载到服务器上，创建zip文件并下载它们。

       <?php 
       if(isset($_POST['createZip'])){
        $post = $_POST;   
        $file_folder = "ZipFIle"; // folder to load files
        //downloading on my server
            foreach($post['files'] as $file){
            $ch = curl_init($file);
            $fp = fopen($file_folder.basename($file), 'wb');
            curl_setopt($ch, CURLOPT_FILE, $fp);
            curl_setopt($ch, CURLOPT_HEADER, 0);
            curl_exec($ch);
            curl_close($ch);
            fclose($fp); 
        }
      if(extension_loaded('zip')){  // Checking ZIP extension is available
        if(isset($post['files']) and count($post['files']) > 0){  
         // Checking files are selected
          $zip = new ZipArchive();      // Load zip library 
          $zip_name = "ZipFIle.zip";      // Zip name
          if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){  
          // Opening zip file to load files
            $error .=  "Sorry ZIP creation failed at this time";
          }
          $dir = new DirectoryIterator("ZipFIle"); 
          foreach ($dir as $fileinfo) {
            if (!$fileinfo->isDot()) {
                //var_dump($fileinfo->getFilename());
                $imgfile = $fileinfo->getFilename();
                foreach($post['files'] as $file){
                  if ( basename($file) ==  $imgfile) {
                    //get file and add it to zip
                    $zip->addFile($file_folder.$imgfile);// Adding files into zip
                  }
                }//foreach($post['files'] as $file)
              }//if
          }        
          $zip->close();
          if(file_exists($zip_name)){
            //echo $zip_name ;
            // push to download the zip
            header('Content-type: application/zip');
            header('Content-Disposition: attachment; filename="'.$zip_name.'"');
            readfile($zip_name);
            // remove zip file is exists in temp path
            unlink($zip_name);
            foreach ($dir as $fileInfo) {
                if(!$fileInfo->isDot()) {
                    //delete all files after creating zip
                    unlink($fileInfo->getPathname());
                }
            }//foreach for delete
          }else{echo "no zip";}
        }else
          $error .= "Please select file to zip";
      }else
        $error .= "You dont have ZIP extension";
    }
    ?>
