memcache协程客户端

memcache协程客户端,由swoole 协程client实现

组件要求

• easyswoole/spl: ^1.1

安装方法

composer require easyswoole/memcache

仓库地址

easyswoole/memcache

客户端调用

$config = new \EasySwoole\Memcache\Config([
    'host' => '127.0.0.1',
    'port' => 11211
]);
$client = new EasySwoole\Memcache\Memcache($config);

使用示例:

$config = new \EasySwoole\Memcache\Config([
    'host' => '127.0.0.1',
    'port' => 11211
]);
$client = new EasySwoole\Memcache\Memcache($config);
$client->set('a',1);
$client->get('a');

使用方法:

touch摸一下(刷新有效期)

touch($key, $expiration, $timeout = null)

increment自增KEY

increment($key, $offset = 1, $initialValue = 0, $expiration = 0, $timeout = null)

decrement自减KEY

decrement($key, $offset = 1, $initialValue = 0, $expiration = 0, $timeout = null)

set设置KEY(覆盖)

set($key, $value, $expiration = 0, $timeout = null)

add增加KEY(非覆盖)

add($key, $value, $expiration = 0, $timeout = null)

replace替换一个KEY

replace($key, $value, $expiration = 0, $timeout = null)

append追加数据到末尾

append($key, $value, $timeout = null)

prepend追加数据到开头

prepend($key, $value, $timeout = null)

get获取KEY

get($key, $timeout = null)

delete删除一个key

delete($key, $timeout = null)

stats获取服务器状态

stats($type = null, $timeout = null)

version获取服务器版本

version(int $timeout = null)

flush 清空缓存

flush(int $expiration = null, int $timeout = null)

setMulti 存储多个元素

public function setMulti(array $items, $expiration = null, $timeout = null)

getMulti 检索多个元素

public function getMulti(array $keys, bool $isCas = false, $timeout = null)

cas 检查并设置

public function cas(float $casToken, string $key, $value, int $expiration = null, $timeout = null)

进阶使用

Memcache连接池示例

安装 easyswoole/pool 组件

composer require easyswoole/pool

具体pool相关详细用法可查看 连接池

新增MemcachePool管理器

新增文件/App/Pool/MemcachePool.php

<?php
/**
 * Created by PhpStorm.
 * User: Tioncico
 * Date: 2019/10/15 0015
 * Time: 14:46
 */
namespace App\Pool;
use EasySwoole\Memcache\Memcache;
use EasySwoole\Pool\Config;
use EasySwoole\Pool\AbstractPool;
use EasySwoole\Memcache\Config as MemcacheConfig;
class MemcachePool extends AbstractPool
{
    protected $memcacheConfig;
    /**
     * 重写构造函数,为了传入memcache配置
     * RedisPool constructor.
     * @param Config      $conf
     * @param MemcacheConfig $memcacheConfig
     * @throws \EasySwoole\Pool\Exception\Exception
     */
    public function __construct(Config $conf,MemcacheConfig $memcacheConfig)
    {
        parent::__construct($conf);
        $this->memcacheConfig = $memcacheConfig;
    }
    protected function createObject():Memcache
    {
        //根据传入的memcache配置进行new 一个memcache客户端
        $memcache = new Memcache($this->memcacheConfig);
        return $memcache;
    }
}

注册到Manager中(在initialize事件中注册):

$config = new \EasySwoole\Pool\Config();
$memcacheConfig1 = new \EasySwoole\Memcache\Config(Config::getInstance()->getConf('MEMCACHE1'));
\EasySwoole\Pool\Manager::getInstance()->register(new \App\Pool\MemcachePool($config,$memcacheConfig1),'memcache1');
$memcacheConfig2 = new \EasySwoole\Memcache\Config(Config::getInstance()->getConf('MEMCACHE2'));
\EasySwoole\Pool\Manager::getInstance()->register(new \App\Pool\MemcachePool($config,$memcacheConfig2),'memcache2');

调用(可在控制器中全局调用):

go(function (){
    $memcachePool1 = Manager::getInstance()->get('memcache1');
    $memcachePool2 = Manager::getInstance()->get('memcache2');
    $memcache1 = $memcachePool1->getObj();
    $memcache2 = $memcachePool2->getObj();
    var_dump($memcache1->set('name', '仙士可1'));
    $this->response()->write($memcache1->get('name'));
    var_dump($memcache2->set('name', '仙士可2'));
    $this->response()->write($memcache2->get('name'));
    //回收对象
    $memcachePool1->recycleObj($memcache1);
    $memcachePool2->recycleObj($memcache2);
});
