Just to add to Jeff Bennett's suggestion...
The added benefit of using a PHP script to navigate between pages rather
than a client-side script is that it will work for any browser, even if
scripting is disabled.
For security reasons, a lot of individuals as well as companies disable
Javascript (and VB Script).
Java also requires a runtime environment which may not be installed on
the client machine.
That's why I much prefer the server-side solution.
