    function output_file($file, $name, $mime_type='')
       {
      if(!is_readable($file)) die('File not found or inaccessible!');

         $size = filesize($file);
       $name = rawurldecode($name);

        $known_mime_types=array(
  "html" => "text/html",
         "htm" => "text/html",

Answer 1

我的代码中没有看到任何执行页面重定向的内容。

要执行非常简单的页面重定向，请将其放在流程的最后：

header("Location: index.php");

文件下载后重定向到index.php
