(PECL memcached >= 0.1.0)
Memcached::setMulti — 存储多个元素
$items
[, int $expiration
] )
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。
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
如需要则使用 Memcached::getResultCode()。
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);
?>

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.
