TP3.2.x+thinkphp判断终端访问动态访问模块的实现

手机端访问时调用Mobile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config_mobile.php。

config.php 中：

return array(
    'DEFAULT_MODULE'=>'Home',
    'DEFAULT_CONTROLLER'=>'Index',
    'DEFAULT_ACTION'=>'index',
)

config_mobile.php 中：

return array(
    'DEFAULT_MODULE'=>'Mobile',
    'DEFAULT_CONTROLLER'=>'Index',
    'DEFAULT_ACTION'=>'index',
)

然后在入口文件 index.php 中加入手机端判断方法（建议放到最下面）：

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;
}

然后，我们开始用关键的APP_STATUS来调用不同的模块：
在index.php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_mobile');
}else{
    define('APP_STATUS','Home');
}
