There is user note about it here:
http://www.php.net/manual/en/function.array.php

Similarly to a comment by stlawson at sbcglobal dot net on this page:
http://www.php.net/basic-syntax.instruction-separation

It is usually advisable to define your arrays like this:
$array = array(
     'foo',
     'bar',
);

Note the comma after the last element - this is perfectly legal.
Moreover, it's best to add that last comma so that when you add new
elements to the array, you don't have to worry about adding a comma
after what used to be the last element.

$array = array(
     'foo',
     'bar',
     'baz',
);

But yes, perhaps it should be mentioned in the doc, that the comma at
the end is ok.
