destoon® B2B网站管理系统(以下简称destoon)由西安嘉客信息科技有限责任公司独立研发并推出,对其拥有完全知识产权,中国国家版权局计算机软件著作权登记号:2009SR037570。
系统使用当前流行的PHP语言开发,以MySQL为数据库,采用B/S架构,MVC模式开发。融入了模型化、模板、缓存、AJAX、SEO等前沿技术。与同类产品相比,系统功能更加强大、使用更加简单、运行更加稳定、安全性更强,效率更高,用户体验更好。系统开源发布,便于二次开发、功能整合、个性修改。
代码首先包含common.inc.php文件
在common.inc.php文件中,首先定义常量。
define('IN_DESTOON', true);
define('IN_ADMIN', defined('DT_ADMIN') ? true : false);
define('DT_ROOT', str_replace("\\", '/', dirname(__FILE__)));
if(defined('DT_REWRITE')) include DT_ROOT.'/include/rewrite.inc.php';//是否定义了url伪静态?
$CFG = array();//网站整体配置信息
require DT_ROOT.'/config.inc.php';//-----------------网站配置文件
define('DT_PATH', $CFG['url']);
define('DT_DOMAIN', $CFG['cookie_domain'] ? substr($CFG['cookie_domain'], 1) : '');
define('DT_WIN', strpos(strtoupper(PHP_OS), 'WIN') !== false ? true: false);
define('DT_CHMOD', ($CFG['file_mod'] && !DT_WIN) ? $CFG['file_mod'] : 0);
define('DT_URL', $CFG['url']);//Fox 3.x
define('DT_LANG', $CFG['language']);
define('DT_KEY', $CFG['authkey']);
define('DT_CHARSET', $CFG['charset']);
define('DT_CACHE', $CFG['cache_dir'] ? $CFG['cache_dir'] : DT_ROOT.'/file/cache');
define('DT_SKIN', DT_PATH.'skin/'.$CFG['skin'].'/');
define('SKIN_PATH', DT_PATH.'skin/'.$CFG['skin'].'/');//For 2.x
define('VIP', $CFG['com_vip']);
define('errmsg', 'Invalid Request');
随后加载网站基本功能
$L = array();
include DT_ROOT.'/lang/'.DT_LANG.'/lang.inc.php';//语言信息
require DT_ROOT.'/version.inc.php';
require DT_ROOT.'/include/global.func.php';//--------全局函数
require DT_ROOT.'/include/tag.func.php';//-----------标签函数
require DT_ROOT.'/api/im.func.php';//----------------聊天工具
require DT_ROOT.'/api/extend.func.php';//------------自己写的扩展函数
if(!$MQG && $_POST) $_POST = daddslashes($_POST);
if(!$MQG && $_GET) $_GET = daddslashes($_GET);
if(function_exists('date_default_timezone_set')) date_default_timezone_set($CFG['timezone']);
$DT_PRE = $CFG['tb_pre'];
$DT_QST = $_SERVER['QUERY_STRING'];//----------------querystring
$DT_TIME = time() + $CFG['timediff'];//--------------当前时间
$DT_IP = get_env('ip');
$DT_URL = get_env('url');
$DT_REF = get_env('referer');
$DT_BOT = is_robot();
链接数据库,建立缓存。
header("Content-Type:text/html;charset=".DT_CHARSET);
require DT_ROOT.'/include/db_'.$CFG['database'].'.class.php';//加载数据库类
require DT_ROOT.'/include/cache_'.$CFG['cache'].'.class.php';//加载缓存类
if($_POST) extract($_POST, EXTR_SKIP);//解析post请求的数据
if($_GET) extract($_GET, EXTR_SKIP);//解析get请求的数据
$db_class = 'db_'.$CFG['database'];
$db = new $db_class;
$db->halt = (DT_DEBUG || IN_ADMIN) ? 1 : 0;
$db->pre = $CFG['tb_pre'];
$db->connect($CFG['db_host'], $CFG['db_user'], $CFG['db_pass'], $CFG['db_name'], $CFG['db_expires'], $CFG['db_charset'], $CFG['pconnect']);
$dc = new dcache();
$dc->pre = $CFG['cache_pre'];
加载模块的基本配置
$DT = $MOD = $EXT = $CSS = $DTMP = $CAT = $ARE = $AREA = array();
$CACHE = cache_read('module.php');
if(!$CACHE) {
//没有缓存模块,就读取缓存模块。
require_once DT_ROOT.'/admin/global.func.php';

加载模块,读取模块信息,引入模块文件
