智能判断移动端和电脑浏览器代码

基于移动端的微信和wap网站开发，日益火起来，下面贴一段智能判断分流的代码，希望对菜鸟有所帮助！

<?php
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()) {
echo '手机登录';
header("location:http://www.ratedir.com/wap"); //跳转到移动端网站模块
} else {
echo '电脑登录';
header("location:http://ratedir.com/");//
}
?>

以上是php的代码，如果不管用还可以试试以下JS部分的代码

<script>
var pc_style = ""
var browser = {
versions: function () {
var u = navigator.userAgent, app = navigator.appVersion;
return {
trident: u.indexOf('Trident') > –1,
presto: u.indexOf('Presto') > –1,
webKit: u.indexOf('AppleWebKit') > –1,
gecko: u.indexOf('Gecko') > –1 && u.indexOf('KHTML') == –1,
mobile: !!u.match(/AppleWebKit.*Mobile.*/) || !!u.match(/AppleWebKit/) && u.indexOf('QIHU') && u.indexOf('Chrome') < 0,
ios: !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/),
android: u.indexOf('Android') > –1 || u.indexOf('Linux') > –1,
iPhone: u.indexOf('iPhone') > –1 || u.indexOf('Mac') > –1,
iPad: u.indexOf('iPad') > –1,
webApp: u.indexOf('Safari') == –1,
ua: u
};
}(),
language: (navigator.browserLanguage || navigator.language).toLowerCase()
}
if (browser.versions.mobile && !browser.versions.iPad) {
this.location = "http://wxpt.no1ss.com/weiweb/192/"; //注意此处要修改成为你自己的微网地址
}
</script>
