.htaccess與php判斷手機/電腦訪問手機頁面

首頁頁面為網站更目錄m下，後門參數和pc頁面參數一樣的話就可以這樣，否則可能需要修改一下。
手機訪問電腦頁面時跳轉：

代碼如下	複製代碼
<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>

電腦訪問手機時跳轉：

代碼如下	複製代碼
<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>

最後得說一下，因為RewriteRule ^(.*)$ /m/$1 [L,R=302] [L,R=302]的加入，如果手機頁面中要訪問非手機頁面中的資源時，得用正則排除指定檔案，如： RewriteRule ^(.*?(?<!jpg)$) /m/$1 [L,R=302]，就不會造成手機訪問非手機頁面中jpg圖片時出現無法訪問的問題了。

如果你不能使用.htaccess檔案我們可直接在php中加入下面代碼

代碼如下

//判斷是否屬手機 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 語句

代碼如下	複製代碼
if( is_mobile() ){  就跳到手機頁面哦 } else { 中到PC頁面 }
