"However, this will mean that you will have no capitals at all in your string."

Why not just do a case insensitive search by adding "i" to the end of your regular expression?

/\[b\](.*)\[\/b\]/i

Or worst come to worst, you should be able to group them.

/\[[Bb]\](.*)\[\/[Bb]\]/

Your new code with both possibilities would look like this:

PHP Code:


			
function bbcode($input){

    $pattern[0] = "/\[[Bb]\](.*)\[\/[Bb]\]/";

    $pattern[1] = "/\[url\=(.*)\](.*)\[\/url\]/i";

    

    $replace[0] = "<strong>$1</strong>";

    $replace[1] = "<a href=\"$1\">$2</a>";



    echo preg_replace($pattern, $replace, $input);

}

bbcode("[b]hello![/b] [url=http://localhost/]LOCALHOST!![/url]");

(note: not sure why, but the first B and last URL are capitalized on my end, but they get lowercased on output)
