dede/content_list.php?channelid=1&cid=14

刚开始的时候 (一小时之内 )最下面的计数是 递加 1

也就是缓存 文件 让计数为0  在最初的一个时候 是递加的

content_list.php 大约100行左右

这种东西 好像是超过一个小时 之后 才从缓存中取数据

不过 如果从缓存中取的话  就有个问题   就是

最下面的计算 过了一个小时 它才有更新

unction SetCache($prefix, $key, $value, $timeout = 3600, $is_memcache = TRUE)
    {
        global $cache_helper_config;
        $key = md5 ( $key );
        /* 如果启用MC缓存 */
        if (! empty ( $cache_helper_config['memcache'] ) && $cache_helper_config['memcache'] ['is_mc_enable'] === 'Y' && $is_memcache === TRUE)
        {
            $mc_path = empty ( $cache_helper_config['memcache'] ['mc'] [substr ( $key, 0, 1 )] ) ? $cache_helper_config['memcache'] ['mc'] ['default'] : $cache_helper_config['memcache'] ['mc'] [substr ( $key, 0, 1 )];
            $mc_path = parse_url ( $mc_path );
            $key = ltrim ( $mc_path ['path'], '/' ) . '_' . $prefix . '_' . $key;
            if (empty ( $GLOBALS ['mc_' . $mc_path ['host']] ))
            {
                $GLOBALS ['mc_' . $mc_path ['host']] = new Memcache ( );
                $GLOBALS ['mc_' . $mc_path ['host']]->connect ( $mc_path ['host'], $mc_path ['port'] );
                //设置数据压缩门槛
                //$GLOBALS ['mc_' . $mc_path ['host']]->setCompressThreshold(2048, 0.2);
            }
            
            $result = $GLOBALS ['mc_' . $mc_path ['host']]->set ( $key, $value, MEMCACHE_COMPRESSED, $timeout );
            return $result;
        }
        
        $key = substr ( $key, 0, 2 ) . '/' . substr ( $key, 2, 2 ) . '/' . substr ( $key, 4, 2 ) . '/' . $key;
        $tmp ['data'] = $value;
        $tmp ['timeout'] = $timeout != 0 ? time () + ( int ) $timeout : 0;
        $cache_data = "<?php exit('dedecms');?>\n\r".@serialize ( $tmp );
        return @PutFile ( DEDEDATA . "/cache/$prefix/$key.php",  $cache_data);
    }才有真实的值

if ( ! function_exists('GetCache'))
{
    function GetCache($prefix, $key, $is_memcache = TRUE)
    {
        global $cache_helper_config;
        $key = md5 ( $key );
        /* 如果启用MC缓存 */
        if ($is_memcache === TRUE && ! empty ( $cache_helper_config['memcache'] ) && $cache_helper_config['memcache'] ['is_mc_enable'] === 'Y')
        {
            $mc_path = empty ( $cache_helper_config['memcache'] ['mc'] [substr ( $key, 0, 1 )] ) ? $cache_helper_config['memcache'] ['mc'] ['default'] : $cache_helper_config['memcache'] ['mc'] [substr ( $key, 0, 1 )];
            $mc_path = parse_url ( $mc_path );
            $key = ltrim ( $mc_path ['path'], '/' ) . '_' . $prefix . '_' . $key;
            if (empty ( $GLOBALS ['mc_' . $mc_path ['host']] ))
            {
                $GLOBALS ['mc_' . $mc_path ['host']] = new Memcache ( );
                $GLOBALS ['mc_' . $mc_path ['host']]->connect ( $mc_path ['host'], $mc_path ['port'] );
            }
            return $GLOBALS ['mc_' . $mc_path ['host']]->get ( $key );
        }
        $key = substr ( $key, 0, 2 ) . '/' . substr ( $key, 2, 2 ) . '/' . substr ( $key, 4, 2 ) . '/' . $key;
        $result = @file_get_contents ( DEDEDATA . "/cache/$prefix/$key.php" );
        
        if ($result === false)
        {
            return false;
        }
        $result = str_replace("<?php exit('dedecms');?>\n\r", "", $result);
        $result = @unserialize ( $result );
        
        if($result ['timeout'] != 0 && $result ['timeout'] < time ())
        {
              return false;
        }
        return $result ['data'];
    }
}

以一个小时为限进行判断
