Getting IP Address

[alsaffar]

Hi everybody,

I'm using a function to get my site's users' IP addresses, and its working fine, but one of my users when he logged in, it wrote to the database that the IP address is "unknown"!!!! very wiered!!! Why?

This is the function Im using:

Function GetUserIPAddress()
{
$a = getenv("HTTP_X_FORWARDED_FOR"
$b = getenv("REMOTE_ADDR"
if ($a <> &quot;&quot
{
$posn=0;
do
{
$posn++;
if ($a{$posn} == ',')
{
break;
}
} while ($posn < strlen($a));
$login_ip = substr($a,0,$posn);
} // end [if ($a <> &quot;&quot]
else
{
$login_ip = $b;
}
$login_ip = $login_ip;
return ($login_ip);
}

Is there is anything missing? or can it be more strong?

Please help.

As a start, I would remove the line which reads &quot;$login_ip = $login_ip;&quot;. It really doesn't do much.

Your database has literally the text &quot;unknown&quot; in it?
