PHP to judge the computer access, Mobile Access Example _php Tutorial

So I study how to use PHP to determine whether the Web is a computer access or mobile phone access, and then to load different CSS to achieve the phone and the computer can be normal access to the effect.

Web site looked up a lot of information, and finally found a suitable, more useful code, but also hope to give you a reference.
Copy the Code code 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-', ' 160x160 ', ' 176x220 ', ' 240x240 ', ' 240x320 ', ' 320x ' 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 small series has been tested, can be identified as a computer access or mobile phone access.
