Introduction
PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following excercise..
<?php
//whether ip is from share internet
if (!empty($_SERVER['HTTP_CLIENT_IP']))
{
$ip_address = $_SERVER['HTTP_CLIENT_IP'];
}
//whether ip is from proxy
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$ip_address = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
//whether ip is from remote address
else
{
$ip_address = $_SERVER['REMOTE_ADDR'];
}
echo $ip_address;
?>
<?php
//whether ip is from share internet
if (!empty($_SERVER['HTTP_CLIENT_IP']))
{
$ip_address = $_SERVER['HTTP_CLIENT_IP'];
}
//whether ip is from proxy
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$ip_address = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
//whether ip is from remote address
else
{
$ip_address = $_SERVER['REMOTE_ADDR'];
}
echo $ip_address;
?>
<?php //whether ip is from share internet if (!empty($_SERVER['HTTP_CLIENT_IP'])) { $ip_address = $_SERVER['HTTP_CLIENT_IP']; } //whether ip is from proxy elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { $ip_address = $_SERVER['HTTP_X_FORWARDED_FOR']; } //whether ip is from remote address else { $ip_address = $_SERVER['REMOTE_ADDR']; } echo $ip_address; ?>
