public function CacheBackendInterface::deleteTags

Deletes items with any of the specified tags.

If the cache items are being deleted because they are no longer "fresh", you may consider using invalidateTags() instead. This allows callers to retrieve the invalid items by calling get() with $allow_invalid set to TRUE. In some cases an invalid item may be acceptable rather than having to rebuild the cache.

Parameters

array $tags: Associative array of tags, in the same format that is passed to CacheBackendInterface::set().
