We all know that getting the IP address of the user is a quite easy job in PHP, even in any programming language. But are you sure that you are getting the real IP of the user?
In php, $_SERVER['REMOTE_ADDR'] is used to get the IP address of the user. But what happen if any user from USA access you site via proxy server of Australia. In this case $_SERVER['REMOTE_ADDR'] will return ip address of the Australia rather than ip address of USA.
Note: It is recommended to use above trick to track your user.
