im working on a content management system for that i have to download a php file using php code without executing. any one can help me on this

这是一些像ftp这样的东西。我添加了上传，编辑和下载文件的选项。它工作正常但是下载一个php文件时，它被执行而不是下载...

it is some thing like ftp. i have added the options to upload, edit and download a file. it is working fine. but while downloading a php file it is executed instead of downloading...

我试过的是：

What i tried is:

<?php
$file = $_REQUEST['file_name'];

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));

    include_once($file);
    exit;
}
?>

推荐答案

你必须加载文件内容，写内容请求并设置标题，以便将其解析为强制下载或八位字节流。

You have to load the files content, write the content to the request and set the headers so that it's parsed as force download or octet stream.

例如：

http://server.com/download.php?name=test.php

download.php：

Contents of download.php:

  <?php 
  $filename = $_GET["name"]; //Obviously needs validation
  ob_end_clean();
  header("Content-Type: application/octet-stream; "); 
  header("Content-Transfer-Encoding: binary"); 
  header("Content-Length: ". filesize($filename).";"); 
  header("Content-disposition: attachment; filename=" . $filename);
  readfile($filename);
  die();
  ?>

此代码没有任何修改。虽然它需要验证和一些安全功能。

This code works without any modification. Although it needs validation and some security features.
