Memcached::setMulti

(PECL memcached >= 0.1.0)

Memcached::setMulti — Store multiple items

說明

public bool Memcached::setMulti ( array $items [, int $expiration ] )

Memcached::setMulti() is similar to Memcached::set(), but instead of a single key/value item, it works on multiple items specified in items. The expiration time applies to all the items at once.

參數

items: 存放在伺服器上的鍵／值數組。
expiration: 到期時間，預設為 0。更多訊息參見到期時間。

回傳值

如果成功則回傳 TRUE，失敗則回傳 FALSE。如需要則使用 Memcached::getResultCode()。

範例

Example #1 Memcached::setMulti() example


<?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.
