OK, I have this wonderful regular expression that replaces IP addresses in a variable. The catch is that I want to replace the IP address with the same IP address, just with a link around it that you can click on for further information.

On the example below, I need to replace the $ip with the actual IP address from the expression.

$msg = ereg_replace("([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})", "<a href=\"script.php?$ip\">$ip</a>", $msg);

Can anyone help me?

what exactly you trying to do?

the IP is transfered from script to script over the URL ?

then you want to replace the link on the page with the IP like page.php?ip=iphere

that would be

$ip = $_GET['ip'];

and then in every link just put the ?ip=$ip after the pagename

For each search, you can use \\#

so \\1 should show a part of it.

something like this?

PHP Code:

$ip = '82.181.38.134';
$msg = preg_replace("#((25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9]))#sie", "stripslashes('\<a href=\"page.php?\\1\"\>\\1\</a\>')", $ip);
echo $msg; 


and btw.. the part matching the ip MUST be one long line..
and also i would like to point out that your code also accepts 999.999.999.999 witch is a invalid ip.
hope it helps
