I had a problem of removing session variables in user posted links in a forum.
a usual link would look like this:
index.php?item=forum&
sid=72667a30353433363633303031313434393339343437&
rfz0543663001144939447=f50be7d71e2f8f0312696905ee9decde
I solved it this way:
<?php
//Filter User posted Session IDs an replace it with their own current ID
//in both ways - first name then id or id an then name
//(c) by Grrzzz
$template = preg_replace(
"/rfz([a-z0-9]{19})=([a-z0-9]{32})(\&|\&)sid=([a-z0-9]{44})/",
"{session}",$template);
$template = preg_replace(
"/sid=([a-z0-9]{44})(\&|\&)rfz([a-z0-9]{19})=([a-z0-9]{32})/",
"{session}",$template);
?>
{session} will be replaced by the own user session data later
