No comma after last element in array?

Question

I noticed that some arrays don\'t have a comma after the last item. I have an array:

$first_name = array(
              \'name\'        => \'first_name\',         


        

Answer 1

Both are syntactically correct in a number of languages. The last element is ignored if left blank. It is a nice little easter egg built into languages just so you don't have to keep adding in , before you start modifying an array if you manually have to add a few more values in.
