cut/paste your code and it works for me.
Works for me as well. I get 'no match' from PHP 5.1.2, 5.2.6, and 5.2.8. What
version do you have?
If I might suggest a couple of simplifications that would make it easier to
$url = '/foo(/)?';
I don't think you need parentheses around your second forward-slash. If you had
multiple characters that were optional you'd want to group them in parentheses,
but here I think it just makes the regex harder to read.
Really? I think it makes it crystal clear that it's the '/' that is
optional. In any case, it makes no difference.
echo (preg_match($pattern, $test) != false)
The " != false " here is redundant.
Understood. But what you think is redundancy is, to me, clarity in
programming. I happen to think that boolean tests shouldn't ride on
whether or not an array returned from a function is empty or not (or a
freaking boolean). If what I'm looking for is a "false" then that's what
I'll test for.
Combined with the ternary operator, the logical switchbacks make me a

Oh, you're one of those people who can't stand the sight of a ternary
operator. Buck up, son, it's good for ya ;-)
(Seriously: I don't understand why ternaries freak some people out. It's
plain as day!)
