本文实例讲述了php从memcache读取数据再批量写入mysql的方法。分享给大家供大家参考。具体分析如下:

用 Memcache 可以缓解 php和数据库压力下面代码是解决高负载下数据库写入瓶颈问题,遇到最实用的:写入ip pv uv的时候,用户达到每分钟几万访问量,要记录这些数据,实时写入数据库必定奔溃.

用以下技术就能解决,还有如用户注册,同一时间断内,大量用户注册,可以缓存后一次性写入到数据库,代码如下:

代码如下:

public function cldata(){
$memcache_obj = new Memcache;
    $memcache_obj->connect('127.0.0.1', '11211');
    $all_items = $memcache_obj->getExtendedStats('items');
    foreach($all_items as $option=>$vall){
        if (isset($all_items[$option]['items'])) {
                 $items = $all_items[$option]['items'];
                 foreach ($items as $number => $item) {
                       $str    = $memcache_obj->getExtendedStats('cachedump', $number, 0);
                       $line   = $str[$option];
if(is_array($line) && count($line) > 0){
    foreach($line as $key => $value) {
        $keys[] = $key;
}
}
}
}
}
 
    dump(count($keys));//获取到key
    if(count($keys)>50){//要写入的数据条数      
        $end=50;
    }else{
        $end=count($keys);
    }
     
    for($i=0;$i         if(!strstr($keys[$i],'datadb')) continue;      
        $ksv = str_replace('datadb','',$keys[$i]);
         
    /*$logdata = unserialize(S('login'.$ksv));//登录写入
    if(is_array($logdata)){
        $this->addsuidinlogin($logdata[0],$logdata[1],$logdata[2],1);       
    }   */
         
        /*$sdata = unserialize(S('regadd'.$ksv));//注册写入
    if(is_array($sdata)){
        $this->baiduad($sdata[0],$sdata[1],$sdata[2],$sdata[3],$sdata[4],1);    
    }
    */
        $regdata = unserialize(S('datadb'.$ksv));      
        $ress[]=$regdata;
        S('datadb'.$ksv,null);
     
    }  
    $addb = M()->db(66,C('DB_WEB_AD'));//批量写入 addall
    $addb->table('mj_ad_count')->addall($ress);
    echo M()->getLastSql();   
}


补充:可以使用的工具如:memadmin 还有memadmin 文档.

希望本文所述对大家的php程序设计有所帮助。
