add a condition around the first two echos:

if (getenv("HTTP_X_FORWARDED_FOR") || (getenv("HTTP_CLIENT_IP") ) {
echo "Proxy IP: $ip <BR>";
echo "Host: $fullhost<BR>";
}

echo "Your Real IP Is: $raddr<BR>";
echo "Your Real Host Is: $realhost<BR>";

Try this:

<?php
$ip = $_SERVER['REMOTE_ADDR'];
 if ($_GET['HTTP_X_FORWARDED_FOR'] || $_GET['HTTP_CLIENT_IP']) {
$raddr = $_GET['HTTP_X_FORWARDED_FOR'] ;
$raddr = $_GET['HTTP_CLIENT_IP'];
$realhost = gethostbyaddr($raddr);
             echo "Proxy IP: $ip <BR>";
             echo "Host: $realhost";
} else{

$fullhost = gethostbyaddr($ip);
              echo "Your Real IP Is: $ip<BR>";
              echo "Your Real Host Is:  $fullhost";
}
?>

$raddr= $_GET['HTTP_X_FORWARDED_FOR'];
$realhost = gethostbyaddr($raddr);
             echo "Proxy IP: $raddr <BR>";
             echo "Host: $realhost";
}elseif ($_GET['HTTP_CLIENT_IP']){
$raddr  = $_GET['HTTP_CLIENT_IP'];
$realhost = gethostbyaddr($raddr);
             echo "Proxy IP: $raddr <BR>";
             echo "Host: $realhost";
} else{

hewtluca have you verified that the HTTP_X_FORWARDED_FOR is defined in the superglobal $_GET ? It is typical only located in $_ENV or via getenv()

This should give you the output you wanted:
<?php
$ip = $_SERVER['REMOTE_ADDR'];
$fullhost = gethostbyaddr($ip);
$raddr = trim(getEnv("REMOTE_ADDR")); if (getenv("HTTP_X_FORWARDED_FOR")!="")
$raddr = getenv("HTTP_X_FORWARDED_FOR"); if (getenv("HTTP_CLIENT_IP")!="")
$raddr = getenv("HTTP_CLIENT_IP");
$realhost = gethostbyaddr($raddr);

if (getenv("HTTP_X_FORWARDED_FOR") || (getenv("HTTP_CLIENT_IP") ) {
echo "Proxy IP: $ip <BR>";
echo "Host: $fullhost<BR>";
}

echo "Your Real IP Is: $raddr<BR>";
echo "Your Real Host Is: $realhost<BR>";

I told you I was half a sleep :)  Try this.  I am not actually verifiying these, because I should know them.

<?php

 if ($_SERVER['HTTP_X_FORWARDED_FOR']) {
$raddr= $_SERVER['HTTP_X_FORWARDED_FOR'];
$realhost = gethostbyaddr($raddr);
             echo "Proxy IP: $raddr <BR>";
             echo "Host: $realhost";
}elseif ($_SERVER['HTTP_CLIENT_IP']){
$raddr  = $_SERVER['HTTP_CLIENT_IP'];
$realhost = gethostbyaddr($raddr);
             echo "Proxy IP: $raddr <BR>";
             echo "Host: $realhost";
} else{
$ip = $_SERVER['REMOTE_ADDR'];
$fullhost = gethostbyaddr($ip);
              echo "Your Real IP Is: $ip<BR>";
              echo "Your Real Host Is:  $fullhost";
}
?>

If you only get those two line then the proxy your are using does not forward that information. You might add the following to get more infromation:

if (getenv("HTTP_X_FORWARDED_FOR") || (getenv("HTTP_CLIENT_IP") ) {
echo "Proxy IP: $ip <BR>";
echo "Host: $fullhost<BR>";
} else {
    var_dump($_ENV);
}

Perhaps in the dump you see your real IP adress and in which variable it is stored.
