Cakephp + Predis使用文档
1.环境准备
a.Php环境
b.Capephp 环境
c.Predis文件
2.使用说明
a.predis的URL：http://github.com/nrk/predis/
b.和cakephp集成
取Predis_Compatibility.php、Predis.php、SharedConfigurations.php文件放置于cakephp/app/vendors/Predis目录下
文件修改：
<?php
require_once 'Predis.php';
define('REDIS_HOST', '127.0.0.1');
define('REDIS_PORT', 6379);
$single_server = array(
'host'     => REDIS_HOST,
'port'     => REDIS_PORT//,
//    'database' => 15
);
$multiple_servers = array(
array(
'host'     => '127.0.0.1',
'port'     => 6379,
'database' => 15,
'alias'    => 'first',
),
array(
'host'     => '127.0.0.1',
'port'     => 6380,
'database' => 15,
'alias'    => 'second',
),
);
?>

c.新建Cakephp的components文件redis_client.php
<?php
App::import('Vendor', 'Predis_Client', array('file' =>'Predis'.DS.'SharedConfigurations.php'));
class RedisClientComponent extends Object {
// Predis info
var $redis = null;
//called before Controller::beforeFilter()
function initialize(&$controller, $settings = array()) {
// saving the controller reference for later use
$this->controller =& $controller;
//修改redis
$this->redis = new Predis_Client(array(
'host' => REDIS_HOST,
'port' => REDIS_PORT,
));
//$this->redis = new Predis_Client($single_server);
}
/**
* client add value
*/
function setValue( $key, $val ){
//不存在就添加
if(!$this->redis->exists($key)){
$this->redis->set($key, $val);
}else{
$this->redis->del($key);
$this->redis->set($key, $val);
}
}
/**
* client get value
*/
function getValue($key){
return $this->redis->get($key);
}
/**
* client delete value
*/
function del($key){
if($this->redis->exists($key)){
$this->redis->del($key);
}
}
//called after Controller::render()
function shutdown(&$controller) {
}
}
?>
d.Controller中使用
引入components：
public $components = array('RedisClient');

设置值：
$this->RedisClient->setValue($key, $val);

获得值：
$this->RedisClient->getValue($key);

删除值：
$this->RedisClient->del($key);
