这篇文章主要介绍了PHP 实现判断用户是否手机访问的方法,十分实用的功能,推荐给有需要的小伙伴。
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:
- $agent = check_wap();
- if( $agent )
- {
- header('Location: http://www.phpfensi.com');
- exit;
- }
- // check if wap
- function check_wap(){
- // 先检查是否为wap代理,准确度高
- if(stristr($_SERVER['HTTP_VIA'],"wap")){
- return true;
- }
- // 检查浏览器是否接受 WML.
- elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){
- return true;
- }
- //检查USER_AGENT
- 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'])){
- return true;
- }
- else{
- return false;
- }
- }
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:
- function is_mobile_request()
- {
- $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';
- $mobile_browser = '0';
- if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT'])))
- $mobile_browser++;
- if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))
- $mobile_browser++;
- if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
- $mobile_browser++;
- if(isset($_SERVER['HTTP_PROFILE']))
- $mobile_browser++;
- $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));
- $mobile_agents = array(
- 'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',
- 'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',
- 'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',
- 'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',
- 'newt','noki','oper','palm','pana','pant','phil','play','port','prox',
- 'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',
- 'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',
- 'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',
- 'wapr','webc','winw','winw','xda','xda-'
- );
- if(in_array($mobile_ua, $mobile_agents))
- $mobile_browser++;
- if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false)
- $mobile_browser++;
- // Pre-final check to reset everything if the user is on Windows
- if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false)
- $mobile_browser=0;
- // But WP7 is also Windows, with a slightly different characteristic
- if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false)
- $mobile_browser++;
- if($mobile_browser>0)
- return true;
- else
- return false;
- }
代码很简单,功能很实用,非常适合将其放入项目中,希望小伙伴们能够喜欢。
