PHP 8.3.4 Released!

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.
