any function to trace ip address correctly....?

Hi
i need to trace the ip address of my visitors when they login; i found a function

getenv("REMOTE_ADDR");

PHP:

but when i uploaded a file having this function and ran on my computer i got my ip address: 202.165.255.17
but at the same time i checked ipconfig in cmd and it gave me a different ip:
202.165.254.118

what is the reason that ip address is not correctly given by the function or i should use some other function;

 

Maybe you are accessing the internet via a proxy and the 202.165.255.17 is the proxy address.

 

it may be; i am using dialup and on other isp i get the correct ip address; but with the previous isp my hosting CPanel is showing my correct ip address; what may be the reason...

 

yup it happens sometime.

 

I have found another funtion which is better in some situations; so i am using the two functions with conditional logic ;

two functions i am using are:

$_SERVER['HTTP_X_FORWARDED_FOR']

PHP:

and

$_SERVER['REMOTE_ADDR'] 

PHP:

 

here you go a super duper function for you

/*** FUNCTION GETIP ***/
function getip() {
	if (isSet($_SERVER)) {
 		if (isSet($_SERVER["HTTP_X_FORWARDED_FOR"])) {
  			$realip = $_SERVER["HTTP_X_FORWARDED_FOR"];
 		} 
		else if (isSet($_SERVER["HTTP_CLIENT_IP"])) {
  			$realip = $_SERVER["HTTP_CLIENT_IP"];
 		} 
		else {
  			$realip = $_SERVER["REMOTE_ADDR"];
 		}

	} 
	else {
 		if ( getenv( 'HTTP_X_FORWARDED_FOR' ) ) {
  			$realip = getenv( 'HTTP_X_FORWARDED_FOR' );
 		} 
		else if ( getenv( 'HTTP_CLIENT_IP' ) ) {
  			$realip = getenv( 'HTTP_CLIENT_IP' );
 		} 
		else {
  			$realip = getenv( 'REMOTE_ADDR' );
 		}
	}
return $realip; 
}
/*** FUNCTION GETIP ***/

PHP:

 

$_SERVER['REMOTE_ADDR'] works fine for my codes. Have you gave it a try. There's also another command i don't remember it right now but it is like HTTP_REFERER or something. You might find it on google.

 

just use the function i did there

it works like a charm

 

hmmmm... really super, but

It's necessary to TRACE user, and you'll get 192.168.255.22 from X_FORWARDED_FOR. Better store all.

function getip() {
	$ip = array_unique(array('',$_SERVER["REMOTE_ADDR"],$_SERVER["HTTP_X_FORWARDED_FOR"],$_SERVER["HTTP_CLIENT_IP"]));
	array_shift($ip);
	return(implode(',',$ip));
}

PHP:

 

thank you i needed this
