Just think, you send the page to the clients browser, you (PHP) don´t have
control
what happens on the clients side!
Maybe you can split the functionality in separate, so if the client sends
some vars,
only a part depending on if, else or switch is done by php.
Or (as last option) use JavaScript, which is client side but not always
available.
Best is to redesign your software, pages to avoid such conflicts.
And, if you want to include all users just use html-code wich will work on
most browsers.
