使用PHP、js判断访问是否为手机端，判断访问用户是不是手机端客户端请求头信息
我们在做简单开发的时候，常常需要判断来访者是手机还是 PC。比如之前在写一个 WordPress 小功能的时候只是需要简单判断来访者是 Mac 电脑即执行：
$agent = strtolower($_SERVER['HTTP_USER_AGENT']);
$mac = (strpos($agent, 'mac os x'));
if(!$mac){
echo "不是 Mac 设备！";
} else {
echo "我是执行代码"; //执行所需要运行的代码
}
下面是所有几个最简单的判断代码：
$agent = strtolower($_SERVER['HTTP_USER_AGENT']);
$is_mac = (strpos($agent, 'mac os x')) ? true : false;
$is_pc = (strpos($agent,'windows nt')) ? true:false;
$is_iphone = (strpos($agent,'iphone')) ? true:false;
$is_ipad = (strpos($agent,'ipad')) ? true:false;
$is_android = (strpos($agent,'android')) ? true:false;
if($is_mac){
echo "这是 mac";
}
if($is_pc) {
echo "这是 PC";
}
if($is_iphone) {
echo "这是 iPhone";
}
if($is_ipad) {
echo "这是 iPad";
}
if($is_android) {
echo "这是 Android";
}
js判断是否为手机访问
例子一
<script type="text/javascript">
var ua = navigator.userAgent;
var ipad = ua.match(/(iPad).*OS\s([\d_]+)/),
isIphone =!ipad && ua.match(/(iPhone\sOS)\s([\d_]+)/),
isAndroid = ua.match(/(Android)\s+([\d.]+)/),
isMobile = isIphone || isAndroid;
//判断
if(isMobile){
}else{
}
</script>
例子二
<script>
function browserRedirect() {
var sUserAgent = navigator.userAgent.toLowerCase();
var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
var bIsMidp = sUserAgent.match(/midp/i) == "midp";
var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
var bIsAndroid = sUserAgent.match(/android/i) == "android";
var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
if (!(bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) ){
window.location.href='//www.jb51.net';
}else{
//window.location.href='http://m.jb51.net';
}
}
$(function(){
browserRedirect();
});
</script>
例子三
<script type="text/javascript">
(function(){
var reWriteUrl = function(url){
if(url){
var Splits = url.split("/"),siteName=window.location.pathname;
if(typeof siteName!=="undefined"){
return "http://m.jb51.net"+siteName;
}
}
};
if(/Android|webOS|iPhone|iPad|Windows Phone|iPod|BlackBerry|SymbianOS|Nokia|Mobile/i.test(navigator.userAgent)){
var url=window.location.href;
var pathname=window.location.pathname;
if(url.indexOf("?mobile")<0){
try{
window.location.href=reWriteUrl(url);
}catch(e){}
}
};
})();
</script>
如果需要给搜索引擎看
注意，如果给搜索引擎看的话我们在文件头加入
<meta http-equiv="mobile-agent" content="format=xhtml; url=手机端网址" />
<meta http-equiv="mobile-agent" content="format=html5; url=手机端网址" />
