Replace %20 with spaces when downloading files?

Is it possible to get a url/downloaded file name change the "%20" to spaces? Like instead of downloading the file my%20file.pdf, download my file.pdf? I'd like to use PHP开发者_如何学C if possible...

You will need to make use of the Content-disposition header.

Here's a relevant answer. Here's what the header might look like:

Content-disposition: attachment; filename=my file.pdf

You could also use the reference for the header() function.

I think you can use the Content-Disposition header to force a "Save As" dialog and recommend a file name like so:

header('Content-Disposition: attachment; filename="my file.pdf"');

The PHP.net page on header() seems to suggest the same.
