<code class="php">foreach($files as $file) {
  if (is_dir($dir . '/' . $file)) {
    continue; // 跳过目录

  // 获取文件大小
  $size = filesize($dir . '/' . $file);

  // 创建下载头
  header("Content-Type: application/octet-stream");
  header("Content-Disposition: attachment; filename=\"" . basename($file) . "\"");
  header("Content-Length: " . $size);
