phpempty(php如何获取客户端信息)
一、php如何获取客户端信息
代码入下，只做参考
classuserPCInfo{
//获取客户端浏览器
publicstaticfunctionget_client_browser(){
$sys=$_SERVER['HTTP_USER_AGENT'];//获取用户代理字符串
if(stripos($sys,"Firefox/")>0){
preg_match("/Firefox\/([^;)]+)+/i",$sys,$b);
$exp[0]="Firefox";
$exp[1]=$b[1];//获取火狐浏览器的版本号
}elseif(stripos($sys,"Maxthon")>0){
preg_match("/Maxthon\/([\d\.]+)/",$sys,$aoyou);
$exp[0]="傲游";
$exp[1]=$aoyou[1];
}elseif(stripos($sys,"MSIE")>0){
preg_match("/MSIE\s+([^;)]+)+/i",$sys,$ie);
$exp[0]="IE";
$exp[1]=$ie[1];//获取IE的版本号
}elseif(stripos($sys,"OPR")>0){
preg_match("/OPR\/([\d\.]+)/",$sys,$opera);
$exp[0]="Opera";
$exp[1]=$opera[1];
}elseif(stripos($sys,"Edge")>0){
//win10Edge浏览器添加了chrome内核标记在判断Chrome之前匹配
preg_match("/Edge\/([\d\.]+)/",$sys,$Edge);
$exp[0]="Edge";
$exp[1]=$Edge[1];
}elseif(stripos($sys,"Chrome")>0){
preg_match("/Chrome\/([\d\.]+)/",$sys,$google);
$exp[0]="Chrome";
$exp[1]=$google[1];//获取googlechrome的版本号
}elseif(stripos($sys,'rv:')>0&&stripos($sys,'Gecko')>0){
preg_match("/rv:([\d\.]+)/",$sys,$IE);
$exp[0]="IE";
$exp[1]=$IE[1];
}else{
$exp[0]="未知浏览器";
$exp[1]="";
}
return$exp;
}
//获取客户端操作系统
publicstaticfunctionget_client_os(){
$agent=$_SERVER['HTTP_USER_AGENT'];
$os=false;
if(preg_match('/win/i',$agent)&&strpos($agent,'95')){
$os='Windows95';
}elseif(preg_match('/win9x/i',$agent)&&strpos($agent,'4.90')){

}elseif(preg_match('/win/i',$agent)&&preg_match('/nt6.2/i',$agent)){
$os='Windows8';
}elseif(preg_match('/win/i',$agent)&&preg_match('/nt10.0/i',$agent)){
$os='Windows10';#添加win10判断
}elseif(preg_match('/win/i',$agent)&&preg_match('/nt5.1/i',$agent)){
$os='WindowsXP';
}elseif(preg_match('/win/i',$agent)&&preg_match('/nt5/i',$agent)){

}elseif(preg_match('/NetBSD/i',$agent)){

}elseif(preg_match('/OSF1/i',$agent)){

$os='webzip';
}elseif(preg_match('/offline/i',$agent)){
$os='offline';
}else{
$os='未知操作系统';
}
return$os;
}
//获取ip地址
publicstaticfunctionget_ip(){
//判断服务器是否允许$_SERVER
if(isset($_SERVER)){
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){
$realip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}elseif(isset($_SERVER['HTTP_CLIENT_IP'])){

}else{
$realip=$_SERVER['REMOTE_ADDR'];
}

if(getenv("HTTP_X_FORWARDED_FOR")){

}elseif(getenv("HTTP_CLIENT_IP")){
$realip=getenv("HTTP_CLIENT_IP");
}else{
$realip=getenv("REMOTE_ADDR");
}
}
return$realip;
}
//获取当前ip所在城市
publicstaticfunctionGetIpLookup($ip=''){
if(empty($ip)){
return'请输入IP地址';
}
$test=''.$ip;
$res=@file_get_contents($test);
return$res;
}
}
二、Querywasempty是什么错误
出现querywasempt一般是while错误就代表SQL语句有问题，然后把画面上显示的SQL语句复制下来到phpmyadmin里头运行，看看就知道了，好好看看数据库，数据表这些名字都是否正确。；echo"select*fromshops";；exit();；$query=mysql_query("select*fromshops");
