我赢职场全球经典Thinkphp框架搭建网站功能，用户登录后，如何在前台显示相应的用户名  连接地址：http://dwz.cn/z9NBy

[摘要] 代码中的函数 is_mobile来源于网上，写得挺好的。入口文件通过判断终端类型，定义APP_PATH和APP_NAME，从而执行不同的分组。我要实现的效果是PC和Mobile均用顶级域名访问。当然了，如果你想在手机里实现类似于wap.xxx.com这样的访问，本方法是做不到的，这是thinkphp多域名部署的问题，具体参见tp手册。
用thinkphp框架快速开发一个小型站点还是很方便的，正如本站。菜根网还做了一个手机端的网站，手机浏览器输入本站域名www.icaigen.com查看效果。

下面仅仅讲述在thinkphp的前端引导页面index.php文件中实现平台判断，从而加载不同的分组（或项目）。
//判断是否属手机
function is_mobile(){
    $user_agent = $_SERVER['HTTP_USER_AGENT'];
    $mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte");
    $is_mobile = false;
    foreach ($mobile_agents as $device) {
        if (stristr($user_agent, $device)) {
            $is_mobile = true;
            break;
        }
    }
    return $is_mobile;
}
define('THINK_PATH','./CORE/');
if(is_mobile()){ //跳转至wap分组
    define('APP_NAME','Wap');
    define('APP_PATH','./Wap/');
}else{
    define('APP_NAME','Home');
    define('APP_PATH','./Home/');           
}
define('APP_DEBUG', false);
require THINK_PATH.'core.php';

定义好了入口文件，然后就可以在WAP分组（或项目）下开发手机版网站的代码了。因为是手机版网站，分辨率，图片压缩，网页大小等都是赤裸裸的问题。本人也才接触手机网站建设没几天，就不卖弄了。可以明确的是，PC端网站上非主要的功能在手机网站上都可以砍掉了，比如博客的热门文章，随机文章，评论列表，各种挂件等。
