Memcached::setMulti

(PECL memcached >= 0.1.0)

Memcached::setMulti — 存储多个元素

说明

public Memcached::setMulti ( array $items , int $expiration = ? ) : bool

Memcached::setMulti()类似于Memcached::set()，但是使用了参数items指定多个元素来替代单独的key/value设置以便于对多个元素的操作。expiration 参数指定的时候一次应用到所有的元素上。

参数

items: 存放在服务器上的键／值对数组。
expiration: 到期时间，默认为 0。更多信息请参见到期时间。

返回值

成功时返回 true，或者在失败时返回 false。如需要则使用 Memcached::getResultCode()。

范例

Example #1 Memcached::setMulti() 示例


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

$items = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
);
$m->setMulti($items, time() + 300);
?>

The previous comment is from April 2013, it has a link pointing on current master, so things are changed since 2013 in the source code.



Maybe the right link is

https://github.com/php-memcached-dev/php-memcached/blob/80cb21467a1db6b7b18725df586f11801c823695/php_memcached.c#L1219



By the way, can someone skilled in C confirm the "fake setMulti" problem?

Dont expect setmulti is faster then multiple SETs!

It doesn't use the setmulti lib function, it iterats over every key and send him alone.

I can't find any php implementation with setmulti support (needs support for memcached's binary protocol, remember php's "memcache"-extension only supports text-protocol).

Thats bad, not enought throughput to membase.

So i have to use redis instead, coz of its support for get/set multi.
