這篇文章將為大家詳細講解有關(guān)thinkphp如何判斷訪客為手機端或PC端，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。

創(chuàng)新互聯(lián)建站是一家朝氣蓬勃的網(wǎng)站建設(shè)公司。公司專注于為企業(yè)提供信息化建設(shè)解決方案。從事網(wǎng)站開發(fā)，網(wǎng)站制作，網(wǎng)站設(shè)計，網(wǎng)站模板，微信公眾號開發(fā)，軟件開發(fā)，小程序制作，十載建站對純水機等多個方面，擁有豐富的網(wǎng)站設(shè)計經(jīng)驗。

一、問題：

近日準備給自己的網(wǎng)站做一個小升級,讓用戶在手機二維碼掃描的時候顯示適合手機端來展示的模版【我用的是ThinkPHP3.0】,代碼是參考別人的

二、實現(xiàn)方法：

這里先說下大概的一個思路 簡單兩步:

統(tǒng)版本號和瀏覽器以及它的版本號（貼出的代碼中數(shù)組中只有移動端信息，因此后面只需判斷是否為數(shù)組中的某一個值即可）.

根據(jù)數(shù)組中的值來判斷訪客是否為手機、pad、之類的移動端，如果是的話就規(guī)定項目路徑、名稱為你的手機端模版如

復(fù)制代碼 代碼如下:

define('APP_NAME','mobi');

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

下面代碼的話我盡量加上注釋:

//判斷是否屬手機  
//代碼看上去很多，其實就是數(shù)組里面顯得多而亂，不要被表面現(xiàn)象所嚇倒哦！  
 function is_mobile(){  
    $user_agent = $_SERVER['HTTP_USER_AGENT'];

    $is_mobile = false;  
    foreach ($mobile_agents as $device) {//這里把值遍歷一遍，用于查找是否有上述字符串出現(xiàn)過  
       if (stristr($user_agent, $device)) { //stristr 查找訪客端信息是否在上述數(shù)組中，不存在即為PC端。  
            $is_mobile = true;  
            break;  
        }  
    }  
    return $is_mobile;  
}  
define('THINK_PATH','./CORE/');  
if(is_mobile()){ //跳轉(zhuǎn)至wap分組  
 echo '您是手機端訪問的，已跳轉(zhuǎn)到手機端';  
     define('APP_NAME','mobi');  
    define('APP_PATH','./mobi/');  
}else{  
 echo '你是PC端訪問的';  
     define('APP_NAME','Home');  
    define('APP_PATH','./Home/');           
}
