PHP中利用Redis管道加快執行

$redis->muti($mode)->get($key)->set($key)->exec()；
 既然是這樣的, 也就是說當我要使用管道執行一萬次操做的時候須要寫一萬次操做在muti()的後面,,,仍是我找到更好的寫法？
設計者沒有想到這個問題麼？今天測試成功了

<?
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');
*/

簡單數據mget也能夠實現

 

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`);
