This works in all versions of PHP I've seen, and a similar thing works in Perl
and array initialisation in C.

Its main use is either for programmer laziness (you can just stick a comma on
the end of each item, and you don't have to think about adding or removing
commas if you re-order the values) or to simplify code-generation programs (so
they don't have to worry about not putting a comma on the final item).

It looks a bit funny as a one liner but less so when split across lines,

$a = array(
1,
2,
3,
4,
5,
);

The same doesn't apply to function parameters, though - a trailing comma
produces a parse error.
