| 7 cache.inc | DrupalCacheInterface::clear($cid = NULL, $wildcard = FALSE) |
Expires data from the cache.
If called without arguments, expirable entries will be cleared from the cache_page and cache_block bins.
Parameters
$cid: If set, the cache ID to delete. Otherwise, all cache entries that can expire are deleted.
$wildcard: If set to TRUE, the $cid is treated as a substring to match rather than a complete ID. The match is a right hand match. If '*' is given as $cid, the bin $bin will be emptied.
