clearCache()
clears the cache for a specific template
Description
===========
void
clearCache
string
template
string
cache\_id
string
compile\_id
int
expire\_time
- If you have [multiple caches](#caching.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`](#variable.compile.id) as a third
parameter. You can [group templates together](#caching.groups) so
they can be removed as a group, see the [caching section](#caching)
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.
