php或js判断网站访问者来自手机或者pc机
9月26日，在弄wtuonline的时候为了区分用户是来自手机版浏览器还是pc，针对不同平台选择不同的网站版本，最终总结如下：
一、JS版代码：
<!--切换手机版网站---><script src="/static/webappservice/uaredirect.js" type="text/javascript"></script><script type="text/javascript">uaredirect("/");</script>
//Js方法二
<script type="text/javascript"><!-- //平台、设备和操作系统var system ={win : false,mac : false,xll : false};//检测平台var p = navigator.platform;system.win = p.indexOf("Win") == 0;system.mac = p.indexOf("Mac") == 0;system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);//跳转语句，如果是手机访问就自动跳转到页面if(system.win||system.mac||system.xll){window.location.href="";}else{window.location.href="";}--></script>
二、PHP代码版：
<?php//判断手机还是电脑访问网站方法一：function isMobile() {if (isset ($_SERVER['HTTP_X_WAP_PROFILE'])) {echo "移动设备";}else{echo "PC机";}}
//判断手机还是电脑访问网站方法二：
if (isset ($_SERVER['HTTP_VIA'])) {//找不到为flase,否则为trueif(stristr($_SERVER['HTTP_VIA'], "wap")){echo "移动设备";}else{echo "PC机";}}
//判断手机还是电脑访问网站方法三：
if (isset ($_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');// 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']))) {echo "移动设备";}else{echo "PC机";}}?>
//方法四：综合以上
<?php$mobile_browser = '0';if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {$mobile_browser++;}if((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml')>0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_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-','Googlebot-Mobile');if(in_array($mobile_ua,$mobile_agents)) {$mobile_browser++;}if (strpos(strtolower($_SERVER['ALL_HTTP']),'OperaMini')>0) {$mobile_browser++;}if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows')>0) {$mobile_browser=0;}if($mobile_browser>0) {header("Location: mobile.php"); //手機版}else {header("Location: pc.php"); //電腦版}
下面有为网友总结的前三种方法和优劣分析：

我的最终解决方案选择方法四，综合了前面三种：
pc版的主页：http://domain/index.php
index.php代码：
<?php /**判断是否手机浏览器* @return boolean*/function is_moble(){$mobile_browser = '0';if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {$mobile_browser++;}if((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml')>0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_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-','Googlebot-Mobile');if(in_array($mobile_ua,$mobile_agents)) {$mobile_browser++;}if (strpos(strtolower($_SERVER['ALL_HTTP']),'OperaMini')>0) {$mobile_browser++;}if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows')>0) {$mobile_browser=0;}if($mobile_browser>0) {return true;//header("Location: mobile.php"); //手機版}else {return false;//header("Location: pc.php"); //電腦版}}if(is_moble()){header("Location: /"); //手機版exit();} ?><!doctype html><html lang="en"><head><meta charset="utf-8"><title>武纺大在线</title></head><body>pc版主页。。。。</body></html>
