windows 中memcached安装配置与使用教程

//1. 创建对象
$mem = newMemcache();
//2. 添加服务器
$mem->addServer("192.168.150.250",11211);
$mem->addServer("192.168.150.138",11211);
$mem->addServer("192.168.112.128",11211);
//3. 放置信息
$mem->add("mystr","hello memcache!",MEMCACHE_COMPRESSED,0);
$mem->add("myarray",array(10,20,30,40),MEMCACHE_COMPRESSED,0);
$mem->add("myob",newStu(),MEMCACHE_COMPRESSED,0);
//4. 获取信息
echo $mem->get("mystr")."
";
var_dump($mem->get('myarray'));
echo "
";
$mem->get("myob")->getinfo();
?>

MemCache的实例应用

    //创建memcache对象
    $mem = new Memcache;
 
    //连接memcache服务器
    $mem -> connect("localhost", 11211);
 
    class Test {
        public $a=1;
        public $b=2;
        public $c=3;
    }
 
    $mem -> add("one", "this is memecache test!", MEMCACHE_COMPRESSED, time()+60*60*24*31);
    $mem -> add("two", array("111", "222", "3333"), MEMCACHE_COMPRESSED, 0);
    $mem -> add("three",new Test(), MEMCACHE_COMPRESSED, 0 );
    $mem -> add("four", 100, MEMCACHE_COMPRESSED, 0);
 
    $mem -> set("five", "this is a demo!", MEMCACHE_COMPRESSED, 1000);
 
    var_dump($mem->get("one"));
    echo '
';
 
    var_dump($mem->get("two"));
    echo '
';
 
    var_dump($mem->get("three"));
    echo '

    var_dump($mem->get("five"));
    echo '
';
 
    var_dump($mem->get("four"));
    echo '
';
 
    var_dump($mem->get(array("one", "five")));
    echo '
';
 
    $mem -> delete("one");
    $mem -> delete("two", 0);  
    $mem -> flush();
 
    $mem -> close();

    //数据库的连接和操作
    $sql = "select id, name, pass, age, sex, email from users order by id";
 
    $key=md5($sql);
    //直接从内存memcahce要数据

        $mem -> set($key, $data, MEMCACHE_COMPRESSED, 10);
 
        echo "这是第一次访问从数据库获取的数据并放到了内存中!
