php获得访问来源（手机wap访问、电脑web访问）

为了更好的用户体验，本主题默认支持wap和web两种访问样式，wap访问将不包含任何脚本、样式也是重新撰写，不支持更多页面，只支持首页、详情页， 评论框、登录等内容将陆续更新到wap内容里。如果想测试，您可以使用手机访问http://qianduanblog.com试试看，是不是效果和电脑 访问不一样？

下面贴出获得访问类型的函数（来源于互联网）：

经测试，下面判断是错误的。

1. /***************************************************
2. ** 返回访问的类型（wap web）

4. ***************************************************/
5. function yundanran_get_access_type()
6. {
7. $is_wap=false;
8. // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
9. if (isset($_SERVER['HTTP_X_WAP_PROFILE']))
10. {
11. $is_wap=true;
12. }
13. else
14. {
15. // 如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
16. if(isset($_SERVER['HTTP_VIA']))
17. {
18. // 找不到为flase,否则为true
19. $is_wap=stristr($_SERVER['HTTP_VIA'],"wap") ? true : false;
20. }
21. else
22. {
23. // 协议法，因为有可能不准确，放到最后判断
24. if (isset($_SERVER['HTTP_ACCEPT']))
25. {
26. // 如果只支持wml并且不支持html那一定是移动设备
27. // 如果支持wml和html但是wml在html之前则是移动设备
28. if
29. (
30. (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false)
31. && (strpos($_SERVER['HTTP_ACCEPT'], 'text/html') === false
32. ¦¦ (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') < strpos($_SERVER['HTTP_ACCEPT'], 'text/html')))
33. )
34. {
35. $is_wap=true;
36. }
37. }
38. }
39. }
40. return $is_wap?'wap':'web';
41. }
42. 正确的判断方法，将会近期写出：

    ╮(╯▽╰)╭，笨方法，用UA判断，源自大前端：
