現在web發展速度非常快,各種響應式的站點越來越多,除了APP外,在平時可能需要根據客戶終端訪問來加載不同時模板或跳轉到不同時的域名下,現在分享一個函數,可以做到這樣判斷.android、ios和wp都已經測試過.

PHP實例代碼如下:

1. //判斷moblie 
2. function is_mobile() 
3. { 
4.     $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : ''; 
5.  
6.     $mobile_browser = '0'; 
7.  
8.     if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom|ios)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) 
9.         $mobile_browser++; 
10.  
11.     if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false)) 
12.         $mobile_browser++; 
13.  
14.     if(isset($_SERVER['HTTP_X_WAP_PROFILE'])) 
15.         $mobile_browser++; 
16.  
17.     if(isset($_SERVER['HTTP_PROFILE'])) 
18.         $mobile_browser++; 
19.  
20.     $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4)); 
21.     $mobile_agents = array( 
22.                         'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac', 
23.                         'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',

26.                         'newt','noki','oper','palm','pana','pant','phil','play','port','prox', 
27.                         'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar', 
28.                         'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-', 
29.                         'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp', 
30.                         'wapr','webc','winw','winw','xda','xda-' 
31.                         ); 
32.  
33.     if(in_array($mobile_ua, $mobile_agents)) 
34.         $mobile_browser++; 
35.  
36.     if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false) 
37.         $mobile_browser++; 
38.     // Pre-final check to reset everything if the user is on Windows 
39.     if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false) 
40.         $mobile_browser=0; 
41.  
42.     // But WP7 is also Windows, with a slightly different characteristic 
43.     if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false) 
44.         $mobile_browser++; 
45.  
46.     if($mobile_browser>0) 
47.         return true; 
48.     else 
49.         return false; 
50. }
