PHP uses memcached simple example sharing memcached java memcached official website redis memcached comparison

This article briefly introduces memcached to coders. Memcached is an efficient and fast distributed memory object caching system, mainly used to accelerate WEB dynamic applications. Today, programmers and I will briefly discuss the usage of memcached.

1. Add memcached extension package

<code>php_memcache.dll</code>

2. Add memcached extension in PHP.INI

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

3. Program

<?<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>
