本文章給大家介紹兩種方法來識別訪問你網站是手機用戶不是PC用戶,然后我們根據用戶類型跳到相對應的頁面去,下面先使用htaccess然后學有php的寫法.

首頁頁面為網站更目錄m下,后臺參數和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:

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

電腦訪問手機時跳轉,代碼如下:

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

最后得說一下,因為RewriteRule ^(.*)$ /m/$1 [L,R=302] [L,R=302]的加入,如果手機頁面中要訪問非手機頁面中的資源時,得用正則排除指定文件,如:RewriteRule ^(.*?(?<!jpg)$) /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文件我們可直接在php中加入下面代碼:

1. //判斷是否屬手機 
2. function is_mobile() { 
3.  $user_agent = $_SERVER['HTTP_USER_AGENT']; 
4.  $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"); 
5.  $is_mobile = false; 
6.  foreach ($mobile_agents as $device) { 
7.   if (stristr($user_agent, $device)) { 
8.    $is_mobile = true; 
9.    break; 
10.   } 
11.  } 
12.  return $is_mobile; 
13. } 

第二步:if 語句,代碼如下:

1. if( is_mobile() ){ 
2.  就跳到手機頁面哦 
3. } 
4. else 
5. { 
6. 中到PC頁面 
7. }
