如何下载一个php文件而不执行它?

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...

我尝试的是:

<?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

您必须加载文件内容，将内容写入请求并设置标头，以便将其解析为强制下载或八位字节流.

  <?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();
  ?>
