Detecting @replies and #tags in PHP

[Nobutwhy]

I'm rewriting the twitter module I wrote for my website, to autolink @replies and #hashtags from my twitter feed. This worked fine when it didn't use a loop to detect more than one of each, but when I rewrote it to detect ALL replies/tags, it started to show problems. For instance, I posted " I @think #I @have #it @working #now", and it only detected "#now".

The script's source is here: http://pastie.org/599060

Can anyone tell me what I'm doing wrong here?

Anyone?

As the site's not loading, here's an idea for it:

preg_replace(' ...whatever it starts with... \@(all A-z 0-9 chars) ...whatever preg ends in...', 'http://twitter.com/$1',$tweet);

That might help?
