welcome to the forums! i hope you find a great deal of help here as i have. let's back up a step... in your forums, do you allow HTML to be entered? if so, you may just be able to run strip_tags() with a list of exceptions that you want to allow. that way, if you strip out all <a> tags, you'll get rid of all links. if you're not using HTML, if you can explain what text one has to write to produce a link, we can help you come up with a regex or pattern match to find and remove all links from a given set of text.

good luck!

well, if you want to replace ALL links in a block of text with that image, i would probably do something like this:
[code]
function dieSpammers($String) {
  $find = "|\<a(.+?)\>(.+?)\</a\>|i";
  $replace = "<img src=\"image/hatespammers.gif\" alt=\"(hatespammers)\" />";
  $String = preg_replace($find, $replace, $String);
  return $String;
}

echo dieSpammers($myText);
[/code]
