php运用readfile函数给隐藏下载文件地址增加权限判断
<?php 02 $file = get_file_address();// 文件的真实地址（支持url,不过不建议用url）
03
04 if (file_exists($file)) {
05 header('Content-Description: File Transfer');
06 header('Content-Type: application/octet-stream');
07 header('Content-Disposition: attachment; filename='.basename($file));
08 header('Content-Transfer-Encoding: binary');
09 header('Expires: 0');
10 header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
11 header('Pragma: public');
12 header('Content-Length: ' . filesize($file));
13 ob_clean();
14 flush();
15 readfile($file);
16 exit;
17 }
18 ?>
