Filter Links out of Comments

[koolkat67]

alright, last week I posted a link to my site where people can leave comments and some low-life decided to post links on that page.  Is there someway to filter out links?  I dont really want to use the htmlspecialchars() or the htmlentities() to simply disable them, I want to block them altogether.  Maybe some way to filter out "www" or something?

[only one]

just do it like bbcode

$bbcode = array('www.', '.com', 'www', 'com'); 

$html = array('', '', '', '');

$output = preg_replace($bbcode, $html, $output);

 

please edit bold bits, and you might want to add more things in the bbcode array, like http://  .net  net.

i could go on all day
