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"];
