Memcached::delete

(PECL memcached >= 0.1.0)

Memcached::delete — 删除元素

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

从服务器上删除 key。

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.

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 #1 Memcached::delete() 示例


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

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