function strexists($string, $find) { return !(strpos($string, $find) === false); }
function deep_in_array($value, $array) { 
        foreach($array as $item) {   
            if(!is_array($item)) {   
              if (strpos($value, $item) !== false) {   
                    return true;  
                } else {  continue; } }   
                
            if(in_array($value, $item)) {  
                return true;      
            } else if(deep_in_array($value, $item)) {  
                return true;      
            }  
        }   return false;   }            
            

function mobile() {
    $useragent = strtolower($_SERVER['HTTP_USER_AGENT']);
    $ualist = array('android', 'midp', 'nokia', 'mobile', 'iphone', 'ipod', 'blackberry', 'windows phone');
    if((deep_in_array($useragent, $ualist) || strexists($_SERVER['HTTP_ACCEPT'], "VND.WAP") || strexists($_SERVER['HTTP_VIA'],"wap")))
if(strpos($useragent,'iphone')!==false||strpos($useragent,'ipod')!==false) return '苹果'; else return '安卓';
    else
  return '电脑'; }
