php使用memcached簡單範例分享 memcached java memcached官網 redis memcached 比較

這篇文章簡單向碼農們介紹一下memcached。 memcached 是高效能、快速的分散式記憶體物件快取系統，主要用於加速WEB動態應用程式。今天我和碼農們先來簡單探討下memcached的用法。

1.新增memcached擴充包

<code>php_memcache.dll</code>

2.在PHP.INI加入memcached擴充

<code>extension=php_memcache.dll</code>

3.程式

<?<span>php
    </span><span>//</span><span>创建一个mem对象实例</span><span>$mem</span>=<span>new</span><span> Memcache;
    </span><span>if</span>(!<span>$mem</span>->connect("10.18.110.213",11211<span>)){
        </span><span>die</span>('连接失败!'<span>);
    }
    </span><span>//</span><span>增加
    //1.增加一个字串</span><span>/*</span><span>    if($mem->set('key1',"beijing",MEMCACHE_COMPRESSED,60)){
        echo '添加ok';
    }</span><span>*/</span><span>//</span><span>2.添加数值</span><span>/*</span><span>    if($mem->set('key1',100,MEMCACHE_COMPRESSED,60)){
        echo '添加ok';
    }</span><span>*/</span><span>//</span><span>3.添加数组
    //在添加数组是，根据需要. 希望序列号放入  ,
    //serialize<=>unserialize， 如果根据需要，也可以json_encode <=> json_decode</span><span>$arr</span>=<span>array</span>("bj",'tj'<span>);
    </span><span>if</span>(<span>$mem</span>->set('key1',<span>$arr</span>,MEMCACHE_COMPRESSED,<span>time</span>()+31*3600*24<span>)){
        </span><span>echo</span> '添加数组ok99111'<span>;
    }
    </span><span>//</span><span>4.添加对象</span><span>/*</span><span>    class Dog{
        public $name;
        public $age;
        public function __construct($name,$age){
            $this->name=$name;
            $this->age=$age;
        }
    }
    $dog1=new Dog('小狗',50);
    if($mem->set('key1',$dog1,MEMCACHE_COMPRESSED,60)){
        echo '添加对象ok';
    }</span><span>*/</span><span>//</span><span>5.添加null 布尔值</span><span>/*</span><span>    if($mem->set('key1',false,MEMCACHE_COMPRESSED,60)){
        echo '添加布尔ok';
    }</span><span>*/</span><span>//</span><span>6. 资源类型放入.</span><span>/*</span><span>    $con=mysql_connect("127.0.0.1","root","root");
    if(!$con){
        die('连接数据库失败');
    }
    var_dump($con);
    echo "<br/>";
    if($mem->set('key1',$con,MEMCACHE_COMPRESSED,60)){
        echo '添加资源ok';
    }</span><span>*/</span><span>//</span><span>查询</span><span>$val</span>=<span>$mem</span>->get('key1'<span>);
</span><span>//</span><span>修改
    //可以使用replace</span><span>if</span>(<span>$mem</span>->replace("key11",'hello',MEMCACHE_COMPRESSED,60<span>)){
        </span><span>echo</span> 'replace ok'<span>;
    }</span><span>else</span><span>{
        </span><span>echo</span> 'replace no ok'<span>;
    }
    </span><span>//</span><span>删除</span><span>echo</span> "<br/>"<span>;
    </span><span>if</span>(<span>$mem</span>->delete('key14'<span>)){
        </span><span>echo</span> 'key14 删除'<span>;
    }</span><span>else</span><span>{
        </span><span>echo</span> 'key14不存在'<span>;
    }</span>
