This article mainly introduces the method of Thinkphp to distinguish the mobile terminal and the PC terminal through an entry file. Friends who need it can refer to it

No more nonsense, I will directly post the code for everyone, the specific code As shown below:

<?php
// 检测PHP环境
if(version_compare(PHP_VERSION,&#39;5.3.0&#39;,&#39;<&#39;)) die(&#39;require PHP > 5.3.0 !&#39;);
// 开启调试模式 建议开发阶段开启 部署阶段注释或者设为false
define(&#39;APP_DEBUG&#39;,True);
define(&#39;MULTI_MODULE&#39;, false);
// 获取当前文件所在的目录
define(&#39;DKSITE_TSDIR&#39;, dirname(__FILE__));
// 定义应用目录
define(&#39;APP_PATH&#39;,DKSITE_TSDIR.&#39;/Application/&#39;);
//
function is_mobile(){ 
  $user_agent = $_SERVER[&#39;HTTP_USER_AGENT&#39;];
  $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; 
}
//判断
if(is_mobile()){
 echo &#39;您当前是在：手机端&#39;; 
  // 手机端模块
 define(&#39;BIND_MODULE&#39;,&#39;Mobile&#39;);
}else{ 
 echo &#39;您当前是在：pc端&#39;;
  // pc端前台模块
 define(&#39;BIND_MODULE&#39;,&#39;Home&#39;);      
} 
// 引入ThinkPHP入口文件
require dirname(__FILE__).&#39;/ThinkPHP/ThinkPHP.php&#39;;
