dedecms框架分析，对于plus/list.php 入口文件写法研究它的写法原理。

<?php
//引入配置文件
require_once(dirname(__FILE__)."/../include/common.inc.php");
//http://www.dede.com/plus/list.php?tid=1   获得$tid = 1  频道为1
$tid = (isset($tid) && is_numeric($tid) ? $tid : 0);

include(DEDEINC."/arc.listview.class.php");
    //实列化对象文档列表类
    $lv = new ListView($tid);
    echo "<pre>";
    var_dump($lv);

    //对设置了会员级别的栏目进行处理
    // 内容模型列表类 + 栏目连接类 $this->Fields = $this->TypeLink->TypeInfos;  
    if(isset($lv->Fields['corank']) && $lv->Fields['corank'] > 0)
    {
        require_once(DEDEINC.'/memberlogin.class.php');
        $cfg_ml = new MemberLogin();
        if( $cfg_ml->M_Rank < $lv->Fields['corank'] ) 
        {
            $dsql->Execute('me' , "SELECT * FROM `#@__arcrank` ");
