------ Solution --------------------
Content-type not configured
------ Solution --------------------
What about Firefox?
How to access it? Is the php file stored in the following directory?
------ Solution --------------------
For IE9, the url of a download dialog box is always displayed.
Run the following code:
$ S = file_get_contents ('actual URL ');
Echo base64_encode (substr ($ s, 0,100 ));
Post result

Or provide a valid link.



------ Solution --------------------
I know what's going on,
The configuration of the php. ini file is incorrect. the dll file for loading the php extension is incorrect. Check the php runtime environment.
