thanks for that, thats what i was looking for, but things are more complicated.

it seems that it wont work for a string that has no spaces

for example:

$eg="hello mark";
echo str_replace(" mark", " joe", $eg);

works fine but:

$ip=$_SERVER["REMOTE_ADDR"];
echo str_replace(" ffff", " ", $ip);

does nothing...
how do i make it to search the string for a specific character?

i tried looking at split and eregi functions but i dont unrestdand them enough to make my script work..

having thought a bit more...

if ALL IP's come out with the ffff bit, you could use the following code to retrieve the actual IP:

<?php
$txt = "::ffff:***.**.***.**";
$tmpline=explode(":",$txt);
$ip = $data[$tmpline[0]][ip]=$tmpline[3];

echo $ip; ?>

This basically gives you the txt after the 3rd :

You can make $txt your actual $_SERVER[] information by simply changing the variable.

As it is, this code just echo's "***.**.***.**"
