TP3.2.x判断手机端访问，同一个域名在PC和手机端展示不同模板(半独立式网站)

首先介绍APP_STATUS内置常量，TP入口文件增加APP_STATUS 参数，  自动加载不同的项目配置文件，通过配置文件指向不同的模块

手机端访问时调用Wap手机模块，实现在手机端访问时展示出手机网站，无需跳转域名
首先我们在./Application/Common/Conf/ 目录下建立两个公共配置文件：config.php 和Mobie.php

config.php文件中

<?php
return array(
    'DEFAULT_MODULE'=>'Index',
    'DEFAULT_CONTROLLER'=>'Index',
    'DEFAULT_ACTION'=>'index',
);

Mobie.php文件：

<?php
return array(
    'DEFAULT_MODULE'=>'Mobie',
    'DEFAULT_CONTROLLER'=>'Index',
    'DEFAULT_ACTION'=>'index',
);

　　关键在单入口index文件中添加手机端判断方法（方法建议放到最下面），在文件中的21行后面也就是“定义应用目录”结束后，加入代码：

if(is_mobile_request() ){
    define('APP_STATUS','config_wap');
}else{
    define('APP_STATUS','Index');
}

　　这样，就用关键的APP_STATUS来调用不同的模块，is_mobile_request()这样写：

function is_mobile_request(){
    $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';
    $mobile_browser = '0';
    if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT'])))
        $mobile_browser++;
    if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))
        $mobile_browser++;
    if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
        $mobile_browser++;
    if(isset($_SERVER['HTTP_PROFILE']))
        $mobile_browser++;
        $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));
        $mobile_agents = array(
            'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',
            'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',
            'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',
            'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',
            'newt','noki','oper','palm','pana','pant','phil','play','port','prox',
            'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',
            'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',
            'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',
            'wapr','webc','winw','winw','xda','xda-'
        );
     if(in_array($mobile_ua, $mobile_agents))
          $mobile_browser++;
     if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false)
          $mobile_browser++;
     // Pre-final check to reset everything if the user is on Windows
     if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false)
          $mobile_browser=0;
     // But WP7 is also Windows, with a slightly different characteristic
     if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false)
          $mobile_browser++;
     if($mobile_browser>0)
          return true;
     else
          return false;
}

　　参考TP文档：http://document.thinkphp.cn/manual_3_2.html#load_config

　　我还查到用JS判断的，没去亲自验证，代码如下：

　　

(function(){
    var res = GetRequest();
    var par = res['index'];
    if(par!='gfan'){
        var ua=navigator.userAgent.toLowerCase();
        var contains=function (a, b){
            if(a.indexOf(b)!=-1){return true;}
        };
        var toMobileVertion = function(){
            window.location.href = '手机站地址'
        }

        if(contains(ua,"ipad")||(contains(ua,"rv:1.2.3.4"))||(contains(ua,"0.0.0.0"))||(contains(ua,"8.0.552.237"))){return false}
        if((contains(ua,"android") && contains(ua,"mobile"))||(contains(ua,"android") && contains(ua,"mozilla")) ||(contains(ua,"android") && contains(ua,"opera"))
    ||contains(ua,"ucweb7")||contains(ua,"iphone")){toMobileVertion();}
    }
})();
function GetRequest() {
   var url = location.search; //获取url中"?"符后的字串
   var theRequest = new Object();
   if (url.indexOf("?") != -1) {
      var str = url.substr(1);
      strs = str.split("&");
      for(var i = 0; i < strs.length; i ++) {
         theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
      }
   }
   return theRequest;
}
