To define someone's IP We have to use the PHP REMOTE_ADDR Superglobal like this,

CODE

<?php $ip=$_SERVER['REMOTE_ADDR'] ?>

But if we want to tell someone's ip we have to do this;

CODE

<b>IP Address= <?php $ip ?></b>

If you just want to have the full thing in PHP we will use this,

CODE

<?php $ip=$_SERVER['REMOTE_ADDR'];
echo "<b>IP Address= $ip</b>"; ?>

You should use $_SERVER['REMOTE_ADDR'] not $REMOTE_ADDR.
$_SERVER['REMOTE_ADDR'] is part of a superglobal, not a function.

http://uk2.php.net/manual/en/reserved.vari...ariables.server <-- better resource than this tutorial.

You could just have used:

CODE

<?php echo $_SERVER['REMOTE_ADDR']; ?>

To display user's IP even with proxy:

CODE

<?php
$ip="";
$ip_proxy="";
if (getenv(HTTP_X_FORWARDED_FOR))
{
   if (getenv(HTTP_CLIENT_IP))
      $ip=getenv(HTTP_CLIENT_IP);
   else
   {
      $ip=getenv(HTTP_X_FORWARDED_FOR);
      $ip_proxy=getenv(REMOTE_ADDR);
   }
}
else
   $ip=getenv(REMOTE_ADDR);
echo $ip;
?>

Alex - removed shorttags, portability is a concern in public forum posts.

I suggest you start using it more. It's probably the best resource for writing scripts/programs in PHP.
