Hmm... didn't we do one of these before?

$var="<p>&nbsp;<a href=hello.html>hello</a> ";
preg_match("/<p>[^<]*<a[^>]*?href=\"?(.*?)(>|\"| )/i", $var, $match);

echo $match[1]."\n";

Okay, this will match a line which has a "<p>" then any characters except a "<" until it hits a "<a". It will ignore any class, onmouseover, etc attributes and match against href= with or without the beginning quote. Grabs the url stopping at either an end quote, a space, or the end of the anchor tag.

I had a really good one bookmarked before my last reinstall. 🙁

Anyway, I'd suggest this one if you can ignore the perl commands and just concentrate on the regex. (Syntax is mostly the same coming from perl.)
