I believe that many people will encounter this situation when implementing the file download function. The intention is to click the download connection and prompt to save the dialog box. this is often counterproductive, for example, a file such as PDF will directly display the actual file content in the browser, instead of prompting to save it. You can solve this problem through the following methods. The code is as follows:


$ Filename = 'path + actual filename ';
// File type
Header ('content-type: application/pdf ');
// Download the display name
Header ('content-Disposition: attachment; filename = "keep file name "');
Readfile ("$ filename ");
Exit ();
?>


The following are common online methods:

The code is as follows:


If (isset ($ link ))
{
Header ("HTTP/1.1 303 See Other ");
Header ("Location: $ link ");
Exit;
}


$ Link is the actual path of the file.
