phpwind源码解析------index.php

phpwind的功能很强悍，设计理念也非常不错，但代码写得有些乱，不过可能是php本身的特点导致，让我们这些写惯了java的开发人员看起来极不习惯，并且源码里的注释少得可怜，只能自己边看边加了，今天看了看了根目录下的index.php，带注释的源码如下：

<?php define('SCR','index'); require_once('global.php'); include_once(D_P.'data/bbscache/cache_index.php'); include_once(D_P.'data/bbscache/forum_cache.php'); //notice //公告处理 $noticedb = array(); foreach ($notice_A as $value) { if ($value['startdate']<=$timestamp && (!$value['enddate'] || $value['enddate']>=$timestamp)) { $value['startdate'] = $value['stime'] ? $value['stime'] : get_date($value['startdate'],'y-m-d'); !$value['url'] && $value['url'] = 'notice.php#'.$value['aid']; $noticedb[$value['aid']] = $value; } } $notice_A = $noticedb; unset($noticedb); $topics = $article = $tposts = 0; $cateid = (int)GetGP('cateid'); $secdomain = null; $m = GetGP('m'); //设置默认主页模式为门户 if (!$cateid && $db_modedomain && $secdomain = array_search($pwServer['HTTP_HOST'], $db_modedomain)) { $cateinfo = explode("_",$secdomain); if ('cate' == $cateinfo[0]) { $cateid = (int)$cateinfo[1]; $db_bbsurl = $_mainUrl; $m = 'area'; } unset($cateinfo); } //根据参数选择模式 selectMode($m); if (defined('M_P') && file_exists(M_P .
