So I studied how to use php to determine whether a web page is accessed by a computer or a mobile phone, and then load different css to achieve the effect of normal access by both mobile phones and computers.

After checking a lot of information on the website, I finally found a suitable and easy-to-use code. I hope it can give everyone a reference.

Copy code The code is as follows:

function check_wap() {
if (isset($_SERVER['HTTP_VIA'])) return true;
if (isset($_SERVER['HTTP_X_NOKIA_CONNECTION_MODE'])) return true;
if (isset($_SERVER['HTTP_X_UP_CALLING_LINE_ID'])) return true;
if (strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0) {
/ / Check whether the browser/gateway says it accepts WML.
$br = "WML";
} else {
$browser = isset($_SERVER['HTTP_USER_AGENT']) ? trim($_SERVER[ 'HTTP_USER_AGENT']) : '';
if(empty($browser)) return true;
$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,$browser) ||
checkSubstrs($mobile_token_list,$browser);
if($found_mobile)
$br ="WML";
else $br = "WWW";
}
if($br == "WML") {
return true;
} else {
return false;
}
}

function checkSubstrs($list,$str){
$flag = false;
for($i=0;$i if(strpos ($str,$list[$i]) > 0){
$flag = true;
break;
}
}
return $flag;
}

if(check_wap()){
echo "wap";
}else{
echo "web";
}

?>

The editor has tested it and it can identify whether it is accessed by computer or mobile phone.
