Memcached::delete — Delete an item
$key
[, int $time = 0
] )
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.
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
The Memcached::getResultCode() will return
Memcached::RES_NOTFOUND if the key does not exist.
