Hi
I was using the following script to get ip address of client, but I
get Welcom ::1 from the following script. How to get the real ip
address?
<?php
function getRealIpAddr()
{
if (!empty($_SERVER['HTTP_CLIENT_IP'])) //check ip from share
internet
{
$ip=$_SERVER['HTTP_CLIENT_IP'];
}
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) //to check ip is
pass from proxy
{
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
$ip=$_SERVER['REMOTE_ADDR'];
}
return $ip;
}
$ip = getRealIpAddr();
echo "Welcome "; echo $ip;
thanks
suresh

If someone is using a proxy on their local machine (perhaps to speed
up network access), that may *BE* the real IP (v6) address (localhost)
as defined by your function. If more than one of
$_SERVER['HTTP_CLIENT_IP']
$_SERVER['HTTP_X_FORWARDED_FOR']
and $_SERVER['REMOTE_ADDR']
are defined, it is not always obvious which one is "real". The
first two can be IP addresses in someone's local network that are
not reachable from the outside. The first two can also be faked.
I recommend logging all three.

Incorrect and not necessary. His line: echo "Welcome "; echo $ip;
is perfectly legitimate, having the proper terminator ";" after the
first echo. A newline is not required between commands.

This is not about string manipulation at all, but simply about code
formatting preferences.

What kind of a backpedaling answer is that? Did you not understand my
response?
