一、问题：

近日准备给自己的网站做一个小升级,让用户在手机二维码扫描的时候显示适合手机端来展示的模版【我用的是ThinkPHP3.0】,代码是参考别人的

二、实现方法：

这里先说下大概的一个思路 简单两步:

统版本号和浏览器以及它的版本号（贴出的代码中数组中只有移动端信息，因此后面只需判断是否为数组中的某一个值即可）.

根据数组中的值来判断访客是否为手机、pad、之类的移动端，如果是的话就规定项目路径、名称为你的手机端模版如

复制代码 代码如下:

define('APP_NAME','mobi');

define('APP_PATH','./mobi/');

下面代码的话我尽量加上注释:

//判断是否属手机  
//代码看上去很多，其实就是数组里面显得多而乱，不要被表面现象所吓倒哦！  
 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 $device) {//这里把值遍历一遍，用于查找是否有上述字符串出现过  
       if (stristr($user_agent, $device)) { //stristr 查找访客端信息是否在上述数组中，不存在即为PC端。  
            $is_mobile = true;  
            break;  
        }  
    }  
    return $is_mobile;  
}  
define('THINK_PATH','./CORE/');  
if(is_mobile()){ //跳转至wap分组  
 echo '您是手机端访问的，已跳转到手机端';  
     define('APP_NAME','mobi');  
    define('APP_PATH','./mobi/');  
}else{  
 echo '你是PC端访问的';  
     define('APP_NAME','Home');  
    define('APP_PATH','./Home/');           
}  
 define('APP_DEBUG', false);  
require THINK_PATH.'core.php';
