This is a simple PHP tutorials and script for getting remote visitors with their IP Address. With this tracking your visitor is very easy and simple with PHP. PHP has a set of global variables. Among them, we use $_SERVER variable to get an IP address of a remote computer. REMOTE_ADDR is the constant that is used to get the IP Address of a remote computer.
Note that this script may not return IP Address if the client/user firewall is on or when client is using some proxy software.
echo "Your IP ADDRESS: ". $ipaddress;
Another way of retrieving IP Address is using function getenv().
$userip = $_SERVER["HTTP_X_FORWARDED_FOR"];
$proxy = $_SERVER["REMOTE_ADDR"];
$host = @gethostbyaddr($_SERVER["HTTP_X_FORWARDED_FOR"]);
Server IP ADDRESS: 188.8.131.52
User IP ADDRESS: 184.108.40.206
User HOST ADDRESS: 220.127.116.11.dynamic.wlink.com.np
Note: $userip is the IP address of the user thats been passed on by the server. $proxy is the IP address of the server itself and $host is the host address of the user. If your PHP version is less than 4.3 then use $HTTP_SERVER_VARS in place of $_SERVER
