PHP中利用Redis管道加快执行

浏览数：192 / 时间：2015年06月09日

$redis->muti($mode)->get($key)->set($key)->exec()；
既然是这样的, 也就是说当我要使用管道执行一万次操作的时候需要写一万次操作在muti()的后面,,,还是我找到更好的写法？
设计者没有想到这个问题么？今天测试成功了

[php] view plain copy

<?
php $redis = new Redis();
$redis->connect(‘10.1.132.86‘, 6379);
$pipe = $redis->multi(Redis::PIPELINE);
for ($i = 0; $i < 10000; $i++) {
$pipe->set("key::$i", str_pad($i, 4, ‘0‘, 0));
$pipe->get("key::$i");
}
$replies = $pipe->exec(); echo " "; print_r($replies);

Description: Enter and exit transactional mode.

Parameters

(optional) Redis::MULTI or Redis::PIPELINE. Defaults toRedis::MULTI. A Redis::MULTI block of commands runs as a single transaction; aRedis::PIPELINE block is simply transmitted faster to the server, but without any guarantee of atomicity.discard cancels a transaction.

Return value

multi() returns the Redis instance and enters multi-mode. Once in multi-mode, all subsequent method calls return the same object untilexec() is called.

Example

$ret = $redis->multi()
    ->set(‘key1‘, ‘val1‘)
    ->get(‘key1‘)
    ->set(‘key2‘, ‘val2‘)
    ->get(‘key2‘)
    ->exec();

/*
$ret == array(
    0 => TRUE,
    1 => ‘val1‘,
    2 => TRUE,
    3 => ‘val2‘);
*/

简单数据mget也可以实现

mGet, getMultiple

Description: Get the values of all the specified keys. If one or more keys dont exist, the array will contain FALSEat the position of the key.

Parameters

Array: Array containing the list of the keys

Return value

Array: Array containing the values related to keys in argument

Examples

$redis->set(‘key1‘, ‘value1‘);
$redis->set(‘key2‘, ‘value2‘);
$redis->set(‘key3‘, ‘value3‘);
$redis->mGet(array(‘key1‘, ‘key2‘, ‘key3‘)); /* array(‘value1‘, ‘value2‘, ‘value3‘);
$redis->mGet(array(‘key0‘, ‘key1‘, ‘key5‘)); /* array(`FALSE`, ‘value2‘, `FALSE`);
