# Nginx 傳遞真實IP

#### **Nginx設定**

**外部IP經過Nginx處理後會變成Nginx的IP，使用$remote\_addr紀錄使用者IP**

```
location /{
           .....
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
```

#### **PHP取得IP設定**

```
if(!empty($_SERVER['HTTP_CLIENT_IP'])){
    $myip = $_SERVER['HTTP_CLIENT_IP'];
}else if(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
    $myip = $_SERVER['HTTP_X_FORWARDED_FOR'];
}else{
    $myip= $_SERVER['REMOTE_ADDR'];
}
```
