POST form to dynamic page name

I've got a simple form with an HTML OPTION block. I'd like to POST the
form to a page whose name is based on the OPTION they select.

So for example say the user selected this option, I'd like to POST the
form to a page named "memory.php".

echo "<option value=\"memory\">Memory Utilization</option>";

Any PHP strategies you could provide would be appreciated. Thanks.
