That's because ^ is not the end-of-string symbol -- it's the START-of-string
symbol. $ is the END-of string symbol. But the OP doesn't need either of
these symbols as he's not trying to match at the start or end of the string,
and nor does he need your suggested leading and trailing (.*?) for the same
reason. Unless anchored with ^ and/or $, preg is perfectly happy to match in
the middle of the subject string.
@Anthony: your pattern is fine -- it's what you're doing with it that's wrong.

I don't see how this is possible, since preg_match returns an integer telling
you how many times the pattern matched -- which will be 0 or 1, since
preg_match doesn't do multiple matches! You also clearly haven't given us your
actual call, since you've only included the pattern and not the subject string.
What you're after is the third argument to preg_match, which returns an array
of matched text; so for:
preg_match("/<div id=result_box> dir=ltr>(.+?)<\\/div>/", $orig, $matches);
$matches[0] will return the entire match (everything from "<div " to "</div>"
$matches[1] will return the first parenthesized expression, which is what
you're looking for.
Note also the doubled backslash, since you need to pass a single backslash
through to escape the / for preg_match. As an alternative, I would strongly
advise using a different delimiter, so that no escaping is needed; for instance:
preg_match("#<div id=result_box> dir=ltr>(.+?)</div>#", $orig, $matches);
Cheers!
