PHP get client IP function


icgit2

Recommended Posts

Hello everyone.
 
Until December my site showed the IP of the client with the following PHP script:
<?
function getRealIP() {
	if (!empty($_SERVER['HTTP_CLIENT_IP']))
		return $_SERVER['HTTP_CLIENT_IP'];
		
	if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
		return $_SERVER['HTTP_X_FORWARDED_FOR'];
	
	return $_SERVER['REMOTE_ADDR'];
}
?>

I have noticed that since January that script does not work anymore.
 
What is the problem and how do I solve it?
 
I appreciate your help.
