php或js判断网站访问者来自手机或者pc

php或js判断网站访问者来自手机或者pc机

2013年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="http://siteapp.baidu.com/static/webappservice/uaredirect.js" type="text/javascript"></script>
  <script type="text/javascript">uaredirect("http://www.baidu.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
}

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: http://m.wtuonline.cn/"); //手機版
exit();
