    Memcached::delete

    (PECL memcached >= 0.1.0)

    Memcached::delete — 删除元素

    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

    成功时返回 true， 或者在失败时返回 false。 如果 key 不存在, Memcached::getResultCode() 将会返回 Memcached::RES_NOTFOUND。

    示例

    示例 #1 Memcached::delete() 示例

    <?php
    $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.
