[IDEA] date_moonrise, date_moonset, and date_moon_info for calculating moonrise and moonset

I did a search thru all places on php.net for moonrise and moonset functions or any comments about moonrise and moonset. I can not find anything about moonrise and moonset. I am not sure where to submit my ideas. I would like to suggest to php developers to add in the moonrise and moonset functions. I think the moonrise and moonset functions should be added in php. date_moonrise date_moonset date_moon_info those functions would be great to have in future version of php.
