PHP下载PDF抛出错误

Question

我有一个PHP文件强制下载PDF文件，在一台服务器（Linux）上它工作正常，但当我将该网站移动到另一台服务器（Win）时，它开始出现此错误：

PHP Warning: readfile(./forms/Form.pdf) 
[<a href='function.readfile'>function.readfile</a>]: 
failed to open stream: No such file or directory in 
D:\CustomerData\webspaces\webspace\wwwroot\Form.php 
on line 4 

的PHP文件中有这样的：

<?php 
header('Content-disposition: attachment; filename=./forms/Form.pdf'); 
header('Content-type: application/pdf'); 
readfile('./forms/Form.pdf'); 
?> 

谢谢！

Answer 1

尝试使用绝对文件位置。我认为这个错误是因为文件路径

请尝试下面的代码。

$file = <absolute file path>; 
header('Content-Description: File Transfer'); 
header('Content-Type: application/pdf'); 
header('Content-Disposition: attachment; filename='.basename($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($file)); 
print_r(headers_list()); 
readfile($file);
