php判断移动端
functionisMobile()
{
//如果有HTTP_X_WAP_PROFILE则一定是移动设备
if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
{
returntrue;
}
//如果HTTP_VIA含有wap则一定是移动设备,部分服务商会屏蔽该信息
if(isset($_SERVER['HTTP_VIA']))
{
//找不到为flase,否则为true
returnstristr($_SERVER['HTTP_VIA'],"wap")?true:false;
}
// 判断手机发送的客户端标志
if(isset($_SERVER['HTTP_USER_AGENT']))
{

}
//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

⑵ 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。
⑶ php怎么判断访问端是移动端还是pc端
2002年到2010年这之间php异军突起的主要原因，是因为互联网尤其是pc端的崛起，那时快速迭代开发，是所有中小企业最大的需求，管你什么接口速度，运行效率，单线程还是多线程库多还是库少，只要能在短时间内把网站搞起来就行。
直到2010年以后移动端的出现app的使用大幅度超过pc端，前后端开始逐步分离，php本身可以嵌入html代码就不再是特别大的优势了，尤其php对进程线程协程的支持不够使得一些app性能需求无法满足，因此php更多开始和其他语言混用，甚至被其他像go，python这样的语言压制并抢占份额。
虽然说总体上我对php的发展还是乐观的，毕竟社区，体量，易用性摆在那里，尤其是php8即将诞生。但是随着移动互联网逐渐走向尾声，app开发对性能要求的更高php在某些方面的劣势也越来越明显。因此对于php的培训减少并不奇怪。
⑷ php如何判断页面是手机端还是pc端
PHP 有个手机检测的库很出名啊 Mobile-Detect
地址：https://packagist.org/packages/mobiledetect/mobiledetectlib
或者
<?php
functionisMobile(){
$useragent=isset($_SERVER['HTTP_USER_AGENT'])?$_SERVER['HTTP_USER_AGENT']:'';
$useragent_commentsblock=preg_match('|(.*?)|',$useragent,$matches)>0?$matches[0]:'';
functionCheckSubstrs($substrs,$text){
foreach($substrsas$substr){
if(false!==strpos($text,$substr)){
returntrue;
}else{
returnfalse;
}
}
}
$mobile_os_list=array('GoogleWirelessTranscoder','WindowsCE','WindowsCE','Symbian','Android','armv6l','armv5','Mobile','CentOS','mowser','AvantGo','OperaMobi','J2ME/MIDP','Smartphone','Go.Web','Palm','iPAQ');
$mobile_token_list=array('Profile/MIDP','Configuration/CLDC-','160×160','176×220','240×240','240×320','320×240','UP.Browser','UP.Link','SymbianOS','PalmOS','PocketPC','SonyEricsson','Nokia','BlackBerry','Vodafone','BenQ','Novarra-Vision','Iris','NetFront','HTC_','Xda_','SAMSUNG-SGH','Wapaka','DoCoMo','iPhone','iPod');
$found_mobile=CheckSubstrs($mobile_os_list,$useragent_commentsblock)||CheckSubstrs($mobile_token_list,$useragent);
if($found_mobile){
returntrue;
}else{
returnfalse;
}
}
if(isMobile())
echo'phone';
else
echo'pc';
?>
⑸ php判断用户是否使用手机设备
php判断用户是否使用手机第一步：如果你和我一样使用的是wordpress，那就复制到主题的 function.php 文件//判断是否属手机 function is_mobile() { $user_agent = $_SERVER['HTTP_USER_AGENT']; $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","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte"); $is_mobile = false; foreach ($mobile_agents as $device) { if (stristr($user_agent, $device)) { $is_mobile = true; break; } } return $is_mobile; } 第二步：if 语句if( is_mobile() ){ echo "您使用的是手机"; }
⑹ ThinkPHP中判断是手机端还是电脑端访问的方法
一般是通过访问的时候请求来源的header头文件信息来进行判断的，譬如Android的手机访问的话一般都会在hedear头信息里面带上Android这样的信息，同理Iphone、windows phone都会带。
