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( $agent ){ header("Location: //www.rzxsoft.cn"); exit;}// check if wapfunction check_wap(){ // 先检查是否为wap代理，准确度高 if(stristr($_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; }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。
