I was using str_replace()
for other BBCodes, but I'm stuck with the url
portion.
I need to convert:
[url=http://maps.google.com/maps?ie=UTF-8&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&q=brits+pub&near=Pasadena,+CA&fb=1&cid=0,0,17926180203917841249&sa=X&oi=local_result&resnum=1&ct=image]Brits[/url]
to
<a href="ttp://maps.google.com/maps?ie=UTF-8&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&q=brits+pub&near=Pasadena,+CA&fb=1&cid=0,0,17926180203917841249&sa=X&oi=local_result&resnum=1&ct=image">Brits</a>
Why don't you take a look at other BBCode parsers?
Just replacing tags isn't sufficient anyways, since this can (and will) lead to incorrect markup.
