Regular expression to allow for number values between 1-3 digits?

Question

RewriteRule ^gallery/[0-9][0-9][0-9]/$ index.php?gallery_id=$1

It allows for any number that is three digits in length. I do not know how to allow for less than three digits as well (or more than three for that matter).

You want to do something along the lines of

[0-9]{1,3}

There are some excellent examples here. Scroll down to nearly the bottom of the page, there are examples of how the various range selections (not the right term for them) work.

the `{n,m}` construct means "a minimum of n and a maximum of m of the following block" so it reads as "anything 0-9 1 to 3 times" – Erik Aug 22 '10 at 14:10
Thank-you, that worked perfectly and the link you provided is also very helpful. – Mike Moore Aug 22 '10 at 14:21

You could have also used (\d{1,3}). – jcoggins May 12 '17 at 18:18
