Definitely 2, the regex captures two groups!

I’m not so sure about that, could be 1 too.

I recall that the first capturing group counts as one, and if there's a second one, that might make it 2. But what about the full match?

I feel like it could be 3 because of the way the regex is structured, but I could be mixing it up with another example.

I'm not entirely sure, but I remember a similar question where the number of matches was based on the capturing groups.

I think the regex captures two groups, so maybe the $matches array has 2 elements?

I'm a bit confused by this question. I'm not sure which method would be the best approach.

I'm pretty confident the JeOS toolkit has a command line utility, but I'm not sure about the other two. I'll have to guess on those and hope I get at least one right.
