Yes.  There are plenty of productive examples on the Web, for example when 
you download from sourceforge.net and use the additional download link 
(client-side scripting will trigger the download dialog automatically, but 
you can cancel that).

There are several ways.  Another is:

  <?php
    header('Content-Disposition: attachment; filename="foo.bar"'); …
    header('Location: http://download.example/foo.bar');
  ?>

  displayed content

This not just a (PHP) language feature, it is using a language-independent 
HTTP feature.  You can use browser developer tools to inspect the HTTP 
response headers, then use the corresponding PHP functions to achieve the 
same.

Next time, do your homework, please.
