Memcached::flush — Invalidate all items in the cache
Memcached::flush()
invalidates all existing cache items
immediately (by default) or after the
delay
specified. After invalidation none of the items will be returned in
response to a retrieval command (unless it's stored again under the same
key after
Memcached::flush()
has invalidated the items).
The flush does not actually free all the memory taquen up by the existing
items; that will happen gradually as new items are stored.
delay
Number of seconds to wait before invalidating the items.
Returns
true
on success or
false
on failure.
Use
Memcached::guetResultCode()
if necesssary.
