bbcode

Does anyone know how to add more then 2 variables to bbcode ?

I have this:

while(preg_match("/\[hr\]/i",$content)) 
	$content = preg_replace("/\[hr\]/i","<hr>",$content);		

What I want to add is the width,size,alignment

Furthest I get is like this:

while(preg_match("/\[hr(=(center|right|left))?\]/i",$content)) 
	$content = preg_replace("/\[hr(=(center|right|left))?\]/i","<hr align=\"$1\">",$content);

Forgot to mention the bbcode would be like this:

[hr=center]
