With an example string like this
my-example-string-1

I want to get the 1 - it could be any number and the string could be anything, but the part I want will always be a dash followed by a number at the end

What would the regex be to grab the number?

I'd skip the regex and go with explode('-', $str) then use end() and if you're not sure about the numbers, maybe test for is_numeric().  If you have some test cases I'd be glad to see if I can code up a sample.

So damn obvious - shouldn't try to write code when I'm drinking.

I'd use Ray's method also.  Actually I think I have used it.

Actually I just looked again at my SQL and it does this already for me (gets the last number used) - not with it.
It's for ensuring unique URL's so I needed the last counter when not unique.
