昨天 我们做了一个手机网站这个页面在电脑是可以直接访问，但我希望这样来做，如果我的手机页面用电脑访问时自动进入电脑版本页面，如果电脑版本用手机访问时自动进入手机版访问，下面我找到了几种办法，一种是.htaccess)实现的，另一种是利用php实现的。

 

首页页面为网站更目录m下，后门参数和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：

 

<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：

 

<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。

 

如果我们没有apache或 htaccess权限时我们可以使用如php来实例:

 

//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; 

} 

调用方法：

 

if( is_mobile() ){ 

  include('手机访问.php文件即可');exit; 

}
