说明

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

从服务器上删除 key

参数

key

要删除的 key。

time

服务端等待删除该元素的总时间。

注意: 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.

返回值

范例

示例 #1 Memcached::delete() 示例

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

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

--For PECL memcached 2.10--
delete used with second argument 'time' returns false and set the error code and message for invalid arguments unless used without Memcached::OPT_BINARY_PROTOCOL.

getResultCode() and getResultMessage() returns  38 and INVALID ARGUMENTS respectively.
