PHP 判断终端是手机还是电脑访问网站代码

用thinkphp做底层框架，判断客户是用pc访问还是手机访问的。

<?php

$platform = platform();//检测访问平台

//print_r($_SERVER);DIE;

define('FILE_ROOT' , dirname(__FILE__));

define('APP_DEBUG' , true);

define('__BUICK__' , true);//

define('APP_PUBLIC_PATH' , '../Public');

define('THINK_PATH', $platform['THINK_PATH']);

define('APP_NAME'  , $platform['APP_NAME']);

define('APP_PATH'  , $platform['APP_PATH']);

require(THINK_PATH.'/ThinkPHP.php');

/**

* 返回平台参数

* 默认返回PC端配置

*/

$form_key = is_mobile();

return $form[$form_key];
