regex

I have a comma delimited list I want to import into a database, and in some cases the last item is blank:

item1, item2, item3
item1, item2,
item1, item2,

I'd like to replace all of these empty columns with a placeholder value using a regexp

item1, item2, item3
item1, item2, PLACEHOLDER
item1, item2, PLACEHOLDER

I tried preg_replace("/,\n/", ",PLACEHOLDER\n",$csv);, but this isn't working. Anyone know what regexp would work for this?
