PHP判断是否是移动设备的函数

比单一的UA判断要好的多!

可以直接拿来用用!


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',

           );  
     if(in_array($mobile_ua, $mobile_agents))  
       $mobile_browser++;  
     if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false)  
       $mobile_browser++;

     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;
 
}
