php识别手机
‘壹’ php怎么获取手机来自哪个国家
通过读取手机型号。
每一部手机都有自己的型号，根据型号就可以判断手机来自哪个国家。
php语言主要用于Web开发，应用环境相对简单，底层操作较少涉及，所以语法简单，概念比较少，很容易学习和使用。
php提供了许多有用的内置函数，为Web开发提供了很多便利，使代码编写得更好。
‘贰’ PHP如何让网页自动识别是手机还是电脑访问
使用方法：将这个js放在电脑版页面，并修改wap..com为你想要跳转的版本页面
//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..com页面
if(system.win||system.mac||system.xll){
}else{
window.location.href="wap..com";
}
‘叁’ PHP如何识别是电脑端或手机移动端访问网站
用css来判断当前页面的宽度和高度，现在pc的分辨率最低都在1200*768以上，iPad pro的宽度为1024px，当宽度大于1100px以上，都可以认为当前访问端为pc，一般iPad的宽度为768px，iPhone X的宽度为375px；所以当宽度低于800以下的，都视为手机移动端，现在的pc和手机自适应页面都是按照这个来区分的。
‘肆’ 通过PHP 判断用户的设备是否是移动设备
<?php function isMobile(){ //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 return stristr($_SERVER['HTTP_VIA'], "wap") ? true : false; } //判断手机发送的客户端标志,兼容性有待提高 if (isset ($_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' ); if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) { return true; } } return false;} //用法if (isMobile()) { echo "这是手机";}
‘伍’ PHP如何检测手机是什么系统
php判断方法
$user_agent = $_SERVER['HTTP_USER_AGENT'];
//var_mp($user_agent);
if(stristr($_SERVER['HTTP_USER_AGENT'],'Android')) {
//echo '你的手机是：Android系统';
header('Location: IP');
}else if(stristr($_SERVER['HTTP_USER_AGENT'],'iPhone')){
//echo '你的手机是：ISO系统';
header('Location: IP');
}else{
//echo '你使用的是其他系统';
header('Location:IP');
}
‘陆’ PHP怎么判定是否手机浏览
web服务端判断浏览设备，一般是通过userAgent匹配的。在PHP中是
$_SERVER['HTTP_USER_AGENT']
一般大部分框架都提供有request基本处理，在thinkPHP5中使用
request()->isMobile()
判断是否手机设备浏览
如果你使用的php框架（或者没用）没有提供此类判断，可以使用第三方库 Mobile_Detect来做设备类型探测
github:Mobile_Detect
其中examples目录有各种使用范例
这个库不仅可以探测是否手机，还可以探测系统类型，版本，浏览器厂商，版本，判断是手机还是平板 等等。还可以根据手动设置的userAgent做判断
‘柒’ 在 PHP 开发中如何判断用户是否使用手机
PHP通过内置全局变量$_SERVER['HTTP_USER_AGENT']来获取用户信息，包括浏览器信息，操作系统等；判断是否是手机还是电脑终端访问，只需判断他的$_SERVER['HTTP_USER_AGENT']信息是否存在手机终端类型即可。示例如下：
<?php
//1.获取用户浏览器信息等；
$user_agent=$_SERVER['HTTP_USER_AGENT'];
//2.列举常用手机终端类型
$mobile_agents=array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi",
"android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio",
"au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu",

"wireless","xda","xde","zte");
foreach($mobile_agentsas$device){
if(stristr($user_agent,$device)){
//手机访问
$is_mobile=true;
break;
}
}
//判断手机标识是否为真
if($is_mobile){
echo"手机访问！";
}else{
echo"电脑访问！";
}
?>
‘捌’ PHP 怎么识别手机访问
网上现在有三种观点, 一种是基于浏览器发送的 User-Agent, 但明显这种方法是行不通的, 虽然有人列出了大多数的手机发送的User-Agent, 但依然会有很多手机无法识别, 甚至有些手机浏览器不发送User-Agent, 而且也不能保证以后就不会出新牌子.
下面是一个php的例子, 看过之后你就会知道有多么不可靠.
1. function is_wap(){
2. $ua = strtolower($_SERVER['HTTP_USER_AGENT']);
3. $uachar = "/(nokia|sony|ericsson|mot|samsung|sgh|lg|sie|philips|panasonic|alcatel|lenovo|cldc|midp|wap|mobile)/i";
4. if(($ua == '' || preg_match($uachar, $ua))&& !strpos(strtolower($_SERVER['REQUEST_URI']),'wap')){
5. return true;
6. }else{
7. return false;
8. }
9. }
另外一种是判断HTTP_ACCEPT, 这种应该相对可靠一点, 不过HTTP_ACCEPT是非常复杂的, 如果一般的不支持html的浏览器还好说, 你只要判断浏览器支持wml并且不支持html就可以, 但如果浏览器同时支持wml和html那就难办了, 低端手机可能会将wml放到html的前面, 但是很多高端手机或者智能手机对html的支持很好, 所以html也会出现在wml前面.
这是黑莓手机发送的HTTP_ACCEPT
application/vnd.rim.html,
text/html,
application/vnd.wap.xhtml+xml,
text/vnd.sun.j2me.app-descriptor,
image/vnd.rim.png,image/jpeg,
application/x-vnd.rim.pme.b,
application/vnd.rim.ucs,
image/gif;anim=1,
application/vnd.rim.jscriptc;v=0-8-8,
application/x-javascript,
application/vnd.rim.css;v=1,
text/css;media=handheld,
application/vnd.wap.wmlc;q=0.9,
application/vnd.wap.wmlscriptc;q=0.7,
text/vnd.wap.wml;q=0.7,
*/*;q=0.5
夸张吧? 不过的确是很标准的, 开发人员可以根据这个得到很多信息, 但很多手机都没这么标准的, 如果你查看IE或者FF的HTTP_ACCEPT你会发现它很短.
text/html,
application/xhtml+xml,
application/xml;q=0.9,
*/*;q=0.8
同样, 给你个php的例子.
if (isset($_SERVER['HTTP_ACCEPT']) &&
(strpos($_SERVER['HTTP_ACCEPT'],'vnd.wap.wml')!==FALSE)
&& (strpos($_SERVER['HTTP_ACCEPT'],'text/html')===FALSE ||
(strpos($_SERVER['HTTP_ACCEPT'],'vnd.wap.wml') <
strpos($_SERVER['HTTP_ACCEPT'],'text/html'))
)) {//手机访问
readfile('index.wml');
} else readfile('index.htm');
原理：如果浏览器支持WML、而且[不支持HTML]或[WML优先于HTML]，则判定为手机。但实际上这个原理是不正确的.
还有一种是说判断网关或者IP什么的, 但我个人认为这个很不可靠, 手机的联网方式很多, 比如我开发的时候就是用模拟器的.这个应该不用什么例子了, REMOTE_ADDR 就足够了
‘玖’ php怎样识别手机和电脑访问分别跳转到不同的页面
//为true时就是手机访问否则为PC
functionisMobile(){
//如果有HTTP_X_WAP_PROFILE则一定是移动设备
if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
returntrue;
//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($_SERVER['HTTP_VIA'])){
//找不到为flase,否则为true
returnstristr($_SERVER['HTTP_VIA'],"wap")?true:false;
}
//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'])){
$clientkeywords=array('nokia','sony','ericsson','mot','samsung','htc','sgh','lg','sharp','sie-','philips','panasonic','alcatel','lenovo','iphone','ipod','blackberry','meizu','android','netfront','symbian','ucweb','windowsce','palm','operamini','operamobi','openwave','nexusone','cldc','midp','wap','mobile');
//从HTTP_USER_AGENT中查找手机浏览器的关键字
if(preg_match("/(".implode('|',$clientkeywords).")/i",strtolower($_SERVER['HTTP_USER_AGENT'])))
returntrue;
}
//协议法，因为有可能不准确，放到最后判断
if(isset($_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')))){
returntrue;
}
}
returnfalse;
}
‘拾’ PHP可不可以检测出手机的品牌，如三星.小米，苹果，就像qq空间里可以显示出来一样
手机都有一个特有的UA标识
Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.23 Mobile Safari/537.36
上面有关键词Android 、Nexus 5。根据这些关键词去判断手机类型，再对应显示出来具体的型号就可以了。
PHP中UA可以通过$_SERVER['HTTP_USER_AGENT']读到。
判断：
$isIPhone = stripos($_SERVER['HTTP_USER_AGENT'], 'iphone') === false;
UA收集和分析是一项比较繁重的工程。
