You can change <b> and </b> with any other tags according to your requirement.
[PHP]$content = "this is an article content";
echo preg_replace("/(an|content)/i", "<b>\\0</b>", $content);[/PHP]

Heya, Smartic.

I would guess (though I couldn't readily prove) that TheScripts uses URL rewriting to make URLs more readable.

For example:

http://www.thescripts.com/forum/thread701403-dependent+drop.html

Probably gets turned into something like:
http://www.thescripts. com/forum.php?threa d=701404&search[]=dependent&sear ch[]=drop

Then, it's a simple matter of running through $_GET['search'] and modifying the post text as Mwasif explained.
