• If you have multiple caches for a template, you can clear a specific cache by supplying the `cache_id` as the second parameter.
• You can also pass a $compile_id as a third parameter. You can group templates together so they can be removed as a group, see the caching section for more information.

• As an optional fourth parameter, you can supply a minimum age in seconds the cache file must be before it will get cleared.

  > Note > > Since Smarty version 3.1.14 it is possible to delete cache files > by their individual expiration time at creation by passing > constant SMARTY::CLEAR\_EXPIRED as fourth parameter.
