这是我的代码..
<?php
ob_clean();
$params = Zend_Controller_Front::getInstance()->getRequest()->getParams();
// block any attempt to the filesystem
if (isset($params['file']) && basename($params['file']) == $params['file']) {
$filename = $params['file'];
} else {
$filename = NULL;
}
// define error message
$err = '<div class="right-panel fl">

<div class="gradient-box" style="margin-top:20px;" ><p style="color:#990000">Sorry, the file you are requesting is unavailable.</p></div></div>';
if (!$filename) {
// if variable $filename is NULL or false display the message
echo $err;
} else {
// define the path to your download folder plus assign the file name
$path = BASE_PATH.QUESTIONS_FILE_PUBLIC.$filename;
$path2 = REL_PATH.QUESTIONS_FILE.$filename;
// check that file exists and is readable
if (file_exists($path) && is_readable($path)) {

exit;

if ($file) {
// stream the file and exit the script when complete
fpassthru($file);
exit;
} else {
echo $err;
