Need an idea about how to convert bbcode to smilies, images etc

[al9]

Hello guys,

I need an idea about how to convert codes like:

;) :smile2: :lol: :) [b] [/img] [url = http://www.site.com/file.html] [i] [quote] etc

Of course, I can get one symbol from string and check if it's ":" or ";" or "[" and then convert them to some HTML. Or I can get all codes to an array and replace all know codes to HTML, but then I will not be able to convert codes like:

[url = http://www.site.com/file.html]Link title[/url] or [img]282[/img]

I wonder, is there any "smart" way to do it? Also, maybe there is some built-in PHP function or some PECL/PHP classes?

After some googling, I found this:

if you use smarty for templates take a look at this
http://smarty.incutio.com/?page=BBCodePlugin

even if you don't use it you may extract function and use it in your app.
