Memcached::delete — Delete an item
public Memcached::delete ( string $key [, int $time = 0 ] ) : bool
Memcached::delete() deletes the key
from the server. The time
parameter is the amount of time in seconds (or Unix time until which) the client wishes the server to refuse add
and replace
commands for this key. For this amount of time, the item is put into a delete queue, which means that it won't possible to retrieve it by the get
command, but add
and replace
command with this key will also fail (the set
command will succeed, however). After the time passes, the item is finally deleted from server memory. The parameter time
defaults to 0 (which means that the item will be deleted immediately and further storage commands with this key will succeed).
key
The key to be deleted.
time
The amount of time the server will wait to delete the item.
Returns true
on success or false
on failure. The Memcached::getResultCode() will return Memcached::RES_NOTFOUND
if the key does not exist.
