It can't be done in PHP. PHP is server-side only, and knows nothing
about the window dimensions. You would have to use a client-side
scripting language such as javascript to send the information to the
server, then have a program resize based on the javascript input.

But you'll still have problems if the user resizes the window while your
page is displayed.
