get the ip address of users opening my website

Question

I want to track the IP address of the users who are opening my website. I have done lot of googling and even other questions asked on stackoverflow but couldn't find the solution. I actually want to know how to I get the IP address by using

 $_SERVER['REMOTE_ADDR'] or $_SERVER['REMOTE_HOST'] variables.

You just keep $_SERVER['REMOTE_ADDR'] into a variable like $ipaddress=$_SERVER['REMOTE_ADDR']; and if you want to save with user information into database then you can save $ipaddress value, if you want to see then use echo $ipaddress. — Prasannjit

Use $_SERVER['REMOTE_ADDR']

if ($_SERVER['HTTP_CLIENT_IP']!="") { $ip = $_SERVER['HTTP_CLIENT_IP']; } elseif ($_SERVER['HTTP_X_FORWARDED_FOR']!="") { $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; } else { $ip = $_SERVER['REMOTE_ADDR']; }

If your client is connected through proxy server then $_SERVER['REMOTE_ADDR'] just returns the IP address of the proxy server not of the client' machine. This is the closest you can get to client' ip.

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

Your answer is in your question: $_SERVER['REMOTE_ADDR'] will contain the IP of the user accessing your site. Just use it like you'd use any other variable.

For this the answer is simple. just use PHP's $_SERVER["REMOTE_ADDR"] to get the IP of the user who accesses a given page/url
