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( $agent ) header('Location: http://www.phpstudy.net'); exit;// check if wapfunction check_wap(){ // 先检查是否为wap代理，准确度高 if(stristr($_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html' target='_blank'>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; return false; 再给大家分享一个个人使用的function isPhone() { // 如果有HTTP_X_WAP_PROFILE则一定是移动设备 if (isset($_SERVER['HTTP_X_WAP_PROFILE'])) { return true; //如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息 if (isset($_SERVER['HTTP_VIA'])) { //找不到为flase,否则为true if(stristr($_SERVER['HTTP_VIA'], "wap")) return true; //脑残法，判断手机发送的客户端标志,兼容性有待提高 if (isset($_SERVER['HTTP_USER_AGENT'])) { $clientkeywords = array ( 'nokia', 'sony', 'ericsson', 'mot', 'samsung', 'htc', 'sgh', 'lg', 'sharp', 'sie-', 'philips', 'panasonic', 'alcatel', 'lenovo', 'iphone', 'ipod', 'blackberry', 'meizu', 'android', 'netfront', 'symbian', 'ucweb', 'windowsce', 'palm', 'operamini', 'operamobi', 'openwave', 'nexusone', 'cldc', 'midp', 'wap', 'mobile', 'phone', // 从HTTP_USER_AGENT中查找手机浏览器的关键字 if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) { return true; //协议法，因为有可能不准确，放到最后判断 if (isset($_SERVER['HTTP_ACCEPT'])) { // 如果只支持wml并且不支持html那一定是移动设备 // 如果支持wml和html但是wml在html之前则是移动设备 if ((strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false) && (strpos($_SERVER['HTTP_ACCEPT'], 'text/html') === false || (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') strpos($_SERVER['HTTP_ACCEPT'], 'text/html')))) { return true; return false;}以上所述就是本文的全部内容了，希望大家能够喜欢。PHP教程
