PHP中利用Redis管道加快執行

標籤：

$redis->muti($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作的時候需要寫一萬次操作在muti()的後面,,,還是我找到更好的寫法？
設計者沒有想到這個問題嗎？今天測試成功了

[php] view plaincopy 

1. <?  
2. php   $redis = new Redis();   
3. $redis->connect(‘10.1.132.86‘, 6379);    
4. $pipe = $redis->multi(Redis::PIPELINE);   
5. for ($i = 0; $i <  10000; $i++) {   
6.     $pipe->set("key::$i", str_pad($i, 4, ‘0‘, 0));   
7.     $pipe->get("key::$i");   
8. }   
9.       
10.     $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‘);*/

##############

簡單資料mget也可以實現

 

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`);
