本文实例讲述了 php 隐藏实际地址的文件下载方法分享给大家供大家参考具体如下:
下面这段 php 代码可不透露实际的文件下载地址
- function download_document($filename,$path="",$mimetype="application/octet-stream")
- {
- header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
- header("Content-Disposition: attachment; filename = $filename");
- header("Content-Length:" . filesize($pathto . $filename));
- header("Content-Type: $mimetype");
- echo file_get_contents($pathto . $filename);
- }
实现方法二:
- <?php
- $file = "1.txt";// 文件的真实地址 (支持 url, 不过不建议用 url)
- if (file_exists($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));
- ob_clean();
- flush();
- readfile($file);
- exit;
- }
- ?>
希望本文所述对大家的 php 程序设计有所帮助
