PHP to judge the computer access, mobile phone access Examples _php example

So I studied how to use PHP to determine whether the Web page is computer access or mobile access, and then by loading different CSS to achieve the phone and the computer can be normal access to the effect.

Web site looked at a lot of information, and finally found a suitable, more useful code, but also hope to give you a reference.

Copy Code code as follows:

<?php

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 The ', ' 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; $i <count ($list); $i + +) {
if (Strpos ($str, $list [$i]) > 0) {
$flag = true;
Break
}
}
return $flag;
}

if (Check_wap ()) {
echo "WAP";
}else{
echo "Web";
}

?>

Small series has been tested, can be identified is the computer access or mobile access.
