Stores data in the persistent cache.

Parameters

$cid: The cache ID of the data to store.

$data: The data to store in the cache. Complex data types will be automatically serialized before insertion. Strings will be stored as plain text and not serialized.

$expire: One of the following values:

• CACHE_PERMANENT: Indicates that the item should never be removed unless explicitly told to using cache_clear_all() with a cache ID.
• CACHE_TEMPORARY: Indicates that the item should be removed at the next general cache wipe.
• A Unix timestamp: Indicates that the item should be kept at least until the given time, after which it behaves like CACHE_TEMPORARY.
