php或js判断网站访问者来自手机或者pc机

php或js判断网站访问者来自手机或者pc机

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="http://siteapp.baidu.com/static/webappservice/uaredirect.js" type="text/javascript"></script>

　　<script type="text/javascript">uaredirect("http://www.zhuqiaodou.com/");</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wap.baidu.com页面

if(system.win||system.mac||system.xll){

window.location.href="http://www.php186.com";

}else{

window.location.href="http://wap.php186.com";

}

-->

</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true

if(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

}

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://www.zhuqiaodou.com

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:http://www.zhuqiaodou.com"); //手機版

exit();

}
