Converting BBcode to HTML using php

[Designer]

Dont know if anyone knows of a simple way i can turn BBcode into html?

I'm working on a modification to the portal on my Vbulletin site on which i've just installed an arcade, now im trying to get the arcade news displayed in a module on the portal. just for now i've done it as a temorary page while i get it working (would post a link but its on my PW protected test site).

Anyways, the string returned has BBcode in it so im getting something like (spaced it out a little)

[ b]Designer[ /b] is the new [ b]Asteroids Champion[ /b]

What i effectively need to do is change the BBcode to the html equivalent like

< b>Designer< /b> is the new < b>Asteroids Champion< /b>

Does anybody know an easy way to search within the string and replace the BBcode or worst case just strip it out of the string?

Ignore this, solved it myself

$search=array("[ b]","[ /b]");
		$replace=array("< b>","< /b>");	
	
       	$newsbits = str_replace($search,$replace,$newsbits);
