Ummm, wha about nl2br()? Actually, nl2br() is imperfect - it screws up layouts
because it doesn't really replace newlines, it just adds in a <BR> tag. If you
use an odd font, it can screw up the spacing on the last sentence in a
paragraph. If you don't though, it does exactly the same thing. I'm curious
about the above though - do the numbers represent characters, yeah? So 10 is \n
right, but what's 13? \r? Also, can you use the same syntax in str_replace()? If
you can, you should use that - lower overhead.

Search on phpbuilder.com for terms like "parse" and "url". It's been covered
there plenty of times, so you should be able to pull it from there. I'll have a
look myself later, because I've searched for this before. I can't find the code
though, and I couldn't be arsed trying to write it again... :)
