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：<?phpdefine('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' == $cateinfo) {$cateid = (int)$cateinfo;$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 .
