Smarty REQUEST_URI and regular expressions?

Question

PHP

Hello, there is an if-elseif construct:

{if $smarty.server.REQUEST_URI == '/'}
---
{elseif $smarty.server.REQUEST_URI == '/page_16.html'}
---
{/if}

Can you tell me how to make $smarty.server.REQUEST_URI == '/page_16.html for all pages like page_xxx.html ?
This option does not work:

---
{elseif $smarty.server.REQUEST_URI == '/page_\d+\.html'}
---

You don't need to do this in the template. Do not check the address in it.
Check IDs and compare routes. But not parts of addresses.
