最近有个需求就是获取下本地的ip地址、网上搜索了相关的教程,总结一下分享给大家、有需要的小伙伴可以参考一下
echo $_SERVER['HTTP_USER_AGENT'];
/**
* 获取客户端操作系统信息,包括win10
* @param null
* @return string
*/
<?php
function GetOs() {
if (!empty($_SERVER['HTTP_USER_AGENT'])) {
$OS = $_SERVER['HTTP_USER_AGENT'];
if (preg_match('/win/i', $OS)) {
$OS = 'Windows';
} elseif (preg_match('/mac/i', $OS)) {
$OS = 'MAC';
} elseif (preg_match('/linux/i', $OS)) {
$OS = 'Linux';
} elseif (preg_match('/unix/i', $OS)) {
$OS = 'Unix';
} elseif (preg_match('/bsd/i', $OS)) {
$OS = 'BSD';
} else {
$OS = 'Other';
}
return $OS;
} else {
return "获取访客操作系统信息失败!";
}} ?>
<?php
function GetBrowser() {
if (!empty($_SERVER['HTTP_USER_AGENT'])) {
$br = $_SERVER['HTTP_USER_AGENT'];
if (preg_match('/MSIE/i', $br)) {
$br = 'MSIE';
} elseif (preg_match('/Firefox/i', $br)) {
$br = 'Firefox';
} elseif (preg_match('/Chrome/i', $br)) {
$br = 'Chrome';
} elseif (preg_match('/Safari/i', $br)) {
$br = 'Safari';
} elseif (preg_match('/Opera/i', $br)) {
$br = 'Opera';
} else {
$br = 'Other';
}
return $br;
} else {
return "获取浏览器信息失败!";
}} ?>
<?php
//获取ip
function getip() {
if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP") , "unknown")) {
$ip = getenv("HTTP_CLIENT_IP");
} else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR") , "unknown")) {
$ip = getenv("HTTP_X_FORWARDED_FOR");
} else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR") , "unknown")) {
$ip = getenv("REMOTE_ADDR");
} else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) {
$ip = $_SERVER['REMOTE_ADDR'];
} else {
$ip = "unknown";
}
return $ip;}
补充一下网站使用 CDN 以后无法获取用户真实 IP 的解决方法:
function GetClientIP(){
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
if($ip != ""){
$arr = explode(",",$ip);
return $arr[0];
}else{
return $_SERVER["REMOTE_ADDR"];
