本文章给大家介绍两种方法来识别访问你网站是手机用户不是PC用户,然后我们根据用户类型跳到相对应的页面去,下面先使用htaccess然后学有php的写法.

首页页面为网站更目录m下,后台参数和pc页面参数一样的话就可以这样,否则可能需要修改一下.

手机访问电脑页面时跳转,代码如下:

<IfModule mod_rewrite.c> 
RewriteEngine On 
RewriteBase /m 
RewriteCond %{HTTP_USER_AGENT} "android|blackberry|googlebot-mobile|iemobile|ipad|iphone|ipod|opera mobile|palmos|webos" [NC] 
RewriteRule ^(.*)$ /m/$1 [L,R=302] [L,R=302] 
</IfModule>

电脑访问手机时跳转,代码如下:

<IfModule mod_rewrite.c> 
RewriteEngine On 
RewriteCond %{HTTP_USER_AGENT} "!(android|blackberry|googlebot-mobile|iemobile|ipad|iphone|ipod|opera mobile|palmos|webos)" [NC] 
RewriteRule ^(.*)$ /$1 [L,R=302] 
</IfModule>

最后得说一下,因为RewriteRule ^(.*)$ /m/$1 [L,R=302] [L,R=302]的加入,如果手机页面中要访问非手机页面中的资源时,得用正则排除指定文件,如:RewriteRule ^(.*?(?<!jpg)$) /m/$1 [L,R=302],就不会造成手机访问非手机页面中jpg图片时出现无法访问的问题了.

如果你不能使用.htaccess文件我们可直接在php中加入下面代码:

<?php
//判断是否属手机
function is_mobile() {
    $user_agent = $_SERVER['HTTP_USER_AGENT'];
    $mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte");
    $is_mobile = false;
    foreach ($mobile_agents as $device) {
        if (stristr($user_agent, $device)) {
            $is_mobile = true;
            break;
        }
    }
    return $is_mobile;
}
?>

第二步:if 语句,代码如下:

if (is_mobile()) {
    就跳到手机页面哦
} else {
    中到PC页面
}
