Description

public function Memcached::delete(string $key, int $time = 0): bool

Delete the key from the server.

Parameters

key: The key to be deleted.
time: The amount of time the server will wait to delete the item.

Note:
As of memcached 1.3.0 (released 2009) this feature is no longer supported. Passing a non-zero time will cause the deletion to fail. Memcached::getResultCode() will return MEMCACHED_INVALID_ARGUMENTS.

Returns true on success or false on failure. The Memcached::getResultCode() will return Memcached::RES_NOTFOUND if the key does not exist.

Examples

$m = new Memcached();
$m->addServer('localhost', 11211);

$m->delete('key1');
?>
