PHP CodeBase: 判断用户是否手机访问(转)

随着移动设备的普及，网站也会迎来越来越多移动设备的访问。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。

自定义的函数如下：

01	$agent = check_wap();

02	if( $agent )

03

{

04	header('Location: http://www.nowamagic.net');

05

exit;

06

}

07

08	// check if wap

09	function check_wap(){

10	// 先检查是否为wap代理，准确度高

11	if(stristr($_SERVER['HTTP_VIA'],"wap")){

12	return true;

13

}

14	// 检查浏览器是否接受 WML.

15	elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){

16	return true;

17

}

18	//检查USER_AGENT

19

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'])){

20	return true;

21

}

22

else{

23	return false;

24

}

25

}

再来一个从PHP框架剥离的判断是否为手机移动终端的函数：

view source

print?

01	function is_mobile_request()

02

{

03	$_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ?$_SERVER['ALL_HTTP'] : '';

04	$mobile_browser = '0';

05	if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i',strtolower($_SERVER['HTTP_USER_AGENT'])))

06	$mobile_browser++;

07	if((isset($_SERVER['HTTP_ACCEPT'])) and(strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))

08	$mobile_browser++;

09	if(isset($_SERVER['HTTP_X_WAP_PROFILE']))

10	$mobile_browser++;

11	if(isset($_SERVER['HTTP_PROFILE']))

12	$mobile_browser++;

13	$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));

14	$mobile_agents = array(

15	'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',

16	'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',

17	'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',

18	'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',

19	'newt','noki','oper','palm','pana','pant','phil','play','port','prox',

20	'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',

21	'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',

22	'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',

23	'wapr','webc','winw','winw','xda','xda-'

24

);

25	if(in_array($mobile_ua, $mobile_agents))

26	$mobile_browser++;

27	if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false)

28	$mobile_browser++;

29	// Pre-final check to reset everything if the user is on Windows

30	if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false)

31	$mobile_browser=0;

32	// But WP7 is also Windows, with a slightly different characteristic

33	if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false)

34	$mobile_browser++;

35	if($mobile_browser>0)

36	return true;

37

else

38	return false;

39

}
