smith12us

用适应PC的页面，很多时候对手机用户不友好，那么有些时候，我们需要判断用户是否用手机访问，如果是手机的话，就跳转到指定的手机友好页面。这里就介绍一下，如何判断用户是否用手机访问。
代码:

1. $agent = check_wap();
   
2. 
   
3. if( $agent )
   
4. 
   
5. {
   
6. 
   
7.   header('Location: http://www.aichengxu.com/view/61539');
   
8. 
   
9.   exit;
   
10. 
    
11. }
    
12. 
    
13. // check if wap
    
14. 
    
15. function check_wap(){
    
16. 
    
17.   // 先检查是否为wap代理，准确度高
    
18. 
    
19.   if(stristr($_SERVER['HTTP_VIA'],"wap")){
    
20. 
    
21.       return true;
    
22. 
    
23.   }
    
24. 
    
25.   // 检查浏览器是否接受 WML.
    
26. 
    
27.   elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){
    
28. 
    
29.       return true;
    
30. 
    
31. }
    
32. 
    
33. //检查USER_AGENT
    
34. 
    
35. elseif(preg_match('/(blackberry|configuration\/cldc|hp |hp-|htc |htc_|htc-|iemobile|kindle|midp|mmp|motorola|mobile|nokia|opera mini|opera |Googlebot-Mobile|YahooSeeker\/M1A1-R2D2|android|iphone|ipod|mobi|palm|palmos|pocket|portalmmm|ppc;|smartphone|sonyericsson|sqh|spv|symbian|treo|up.browser|up.link|vodafone|windows ce|xda |xda_)/i', $_SERVER['HTTP_USER_AGENT'])){
    
36. 
    
37.       return true;           
    
38. 
    
39.   }
    
40. 
    
41.   else{
    
42. 
    
43.       return false;  
    
44. 
    
45. }
    
46. 
    
47. }
