通过UA判断手机端还是电脑端实现访问不同的页面/网址

输入网址 1.342600.xyz,如果是电脑端访问显示1.342600.xyz内容，如果是手机端访问则跳转 www.pcno.cn显示。

代码：

<script type="text/javascript">
  function getQueryString(name) { 
    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i"); 
    var r = window.location.search.substr(1).match(reg); 
    if (r !=null) return unescape(r[2]); return ''; 
 } 
  var browser = {
    versions: function() {
    var u = navigator.userAgent, app = navigator.appVersion;
    return {//移动终端浏览器版本信息
    trident: u.indexOf('Trident') > -1, //IE内核
    presto: u.indexOf('Presto') > -1, //opera内核
    webKit: u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核
    gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核
    mobile: !!u.match(/AppleWebKit.*Mobile.*/) || !!u.match(/AppleWebKit/), //是否为移动终端
    ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端
    android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或者uc浏览器
    iPhone: u.indexOf('iPhone') > -1 || u.indexOf('Mac') > -1, //是否为iPhone或者QQHD浏览器
    iPad: u.indexOf('iPad') > -1, //是否iPad
    webApp: u.indexOf('Safari') == -1 //是否web应该程序，没有头部与底部
    };
    }(),
    language: (navigator.browserLanguage || navigator.language).toLowerCase()
    }
    if(getQueryString('nojump') == 1){

    }else{
      if (browser.versions.android || browser.versions.ios) {
        if(!browser.versions.iPad){
        window.location.href = 'https://www.pcno.cn/';
        }

    }
  }
  
</script>

上面的一搬是HTML上食用，虽然PHP也通用。一次折腾Typecho模板的时候需要判断UA访问不同的文件（而不是网址）

原参考代码：

<?php
function is_mobile_request() {
    $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';
    $mobile_browser = '0';
    if (preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) $mobile_browser++;
    if ((isset($_SERVER['HTTP_ACCEPT'])) and(strpos(strtolower($_SERVER['HTTP_ACCEPT']), 'application/vnd.wap.xhtml+xml') !== false)) $mobile_browser++;
    if (isset($_SERVER['HTTP_X_WAP_PROFILE'])) $mobile_browser++;
    if (isset($_SERVER['HTTP_PROFILE'])) $mobile_browser++;
    $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'], 0, 4));
    $mobile_agents = array('w3c ', 'acs-', 'alav', 'alca', 'amoi', 'audi', 'avan', 'benq', 'bird', 'blac', 'blaz', 'brew', 'cell', 'cldc', 'cmd-', 'dang', 'doco', 'eric', 'hipt', 'inno', 'ipaq', 'java', 'jigs', 'kddi', 'keji', 'leno', 'lg-c', 'lg-d', 'lg-g', 'lge-', 'maui', 'maxo', 'midp', 'mits', 'mmef', 'mobi', 'mot-', 'moto', 'mwbp', 'nec-', 'newt', 'noki', 'oper', 'palm', 'pana', 'pant', 'phil', 'play', 'port', 'prox', 'qwap', 'sage', 'sams', 'sany', 'sch-', 'sec-', 'send', 'seri', 'sgh-', 'shar', 'sie-', 'siem', 'smal', 'smar', 'sony', 'sph-', 'symb', 't-mo', 'teli', 'tim-', 'tosh', 'tsm-', 'upg1', 'upsi', 'vk-v', 'voda', 'wap-', 'wapa', 'wapi', 'wapp', 'wapr', 'webc', 'winw', 'winw', 'xda', 'xda-');
    if (in_array($mobile_ua, $mobile_agents)) $mobile_browser++;
    if (strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false) $mobile_browser++;
    if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false) $mobile_browser = 0;
    if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false) $mobile_browser++;
    if ($mobile_browser > 0){
        return true;
    }else{
         return false;
    }
}
if(is_mobile_request()){
    require('./tpl/m/index.html');
}else{
    require('./tpl/pc/index.html');
}
?>

修正后代码：

<?php
function is_mobile_request() {
    $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';
    $mobile_browser = '0';
    if (preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) $mobile_browser++;
    if ((isset($_SERVER['HTTP_ACCEPT'])) and(strpos(strtolower($_SERVER['HTTP_ACCEPT']), 'application/vnd.wap.xhtml+xml') !== false)) $mobile_browser++;
    if (isset($_SERVER['HTTP_X_WAP_PROFILE'])) $mobile_browser++;
    if (isset($_SERVER['HTTP_PROFILE'])) $mobile_browser++;
    $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'], 0, 4));
    $mobile_agents = array('w3c ', 'acs-', 'alav', 'alca', 'amoi', 'audi', 'avan', 'benq', 'bird', 'blac', 'blaz', 'brew', 'cell', 'cldc', 'cmd-', 'dang', 'doco', 'eric', 'hipt', 'inno', 'ipaq', 'java', 'jigs', 'kddi', 'keji', 'leno', 'lg-c', 'lg-d', 'lg-g', 'lge-', 'maui', 'maxo', 'midp', 'mits', 'mmef', 'mobi', 'mot-', 'moto', 'mwbp', 'nec-', 'newt', 'noki', 'oper', 'palm', 'pana', 'pant', 'phil', 'play', 'port', 'prox', 'qwap', 'sage', 'sams', 'sany', 'sch-', 'sec-', 'send', 'seri', 'sgh-', 'shar', 'sie-', 'siem', 'smal', 'smar', 'sony', 'sph-', 'symb', 't-mo', 'teli', 'tim-', 'tosh', 'tsm-', 'upg1', 'upsi', 'vk-v', 'voda', 'wap-', 'wapa', 'wapi', 'wapp', 'wapr', 'webc', 'winw', 'winw', 'xda', 'xda-');
    if (in_array($mobile_ua, $mobile_agents)) $mobile_browser++;
    if (strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false) $mobile_browser++;
    if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false) $mobile_browser = 0;
    if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false) $mobile_browser++;
    if ($mobile_browser > 0){
        return true;
    }else{
         return false;
    }
}
if(is_mobile_request()){
     $this->need('wap_index.php'); 
}else{
    $this->need('pc_index.php'); 
}
?>
