判断手机浏览还是web浏览,并执行相应的动作实例

定位

之前论坛上有会员提到如何区分用户是用手机浏览，还是PC浏览，这里就为大家带来一篇php判断手机浏览还是web浏览,并执行相应的动作简单实例。

通过函数，并调用函数，进行判断，代码如下：
function isMobile(){
  $useragent=isset($_SERVER['HTTP_USER_AGENT']) ? $_SERVER['HTTP_USER_AGENT'] : '';
  $useragent_commentsblock=preg_match('|\(.*?\)|',$useragent,$matches)>0?$matches[0]:'';   
  function CheckSubstrs($substrs,$text){
    foreach($substrs as $substr)
      if(false!==strpos($text,$substr)){
        return true;
      }
      return false;
  }
  $mobile_os_list=array('Google Wireless Transcoder','Windows CE','WindowsCE','Symbian','Android','armv6l','armv5','Mobile','CentOS','mowser','AvantGo','Opera Mobi','J2ME/MIDP','Smartphone','Go.Web','Palm','iPAQ');
  $mobile_token_list=array('Profile/MIDP','Configuration/CLDC-','160×160','176×220','240×240','240×320','320×240','UP.Browser','UP.Link','SymbianOS','PalmOS','PocketPC','SonyEricsson','Nokia','BlackBerry','Vodafone','BenQ','Novarra-Vision','Iris','NetFront','HTC_','Xda_','SAMSUNG-SGH','Wapaka','DoCoMo','iPhone','iPod');

  $found_mobile=CheckSubstrs($mobile_os_list,$useragent_commentsblock) ||
       CheckSubstrs($mobile_token_list,$useragent);

  if ($found_mobile){
    return true;
  }else{
    return false;
  }
}
if (isMobile()){
  header('location: ./app/index.php');//如果为手机端，执行跳转
}
else{
  header('location: ./web/index.php');//如果非手机端，执行跳转
}
