基本使用方法

<?php
    /**
     * Created by PhpStorm.
     * User: raid
     * Date: 2016/7/6
     * Time: 12:03
     */
    
    $m = new Memcached;
    $arr = array(
        array('127.0.0.1', 11211),
        array('127.0.0.2', 11211),
    );
    $m->addServer('127.0.0.1', 11211);
    print_r($m->getStats());
    echo "<br/>";
    print_r($m->getVersion());
    echo "<br/>";
    
    
    $data = array(
        'key' => 'value',
        'key2' => 'value2',
    );
    //$m->setMulti($data, 600);
    $result = $m->getMulti(array('key', 'key2'));
    $m->deleteMulti(array('key', 'key2'));
    //print_r($result);
    echo $m->get('key');
    
    echo $m->getResultCode();
    echo $m->getResultMessage();
    
    //$m->add('mkey', 'mvalue', 600);
    //$m->replace('mkey', 'mvalue2', 1);
    
    //$m->flush();
    
    //$m->set('num', 50, 600);
    
    //$m->increment('num', 5);
    
    $m->decrement('num', 5);
    
    echo $m->get('num');
    
    $m->flush();
