I don't think you would need an if statement, but you would definately need a loop of some sort to cycle through your results from the database.
your sql statement would be something like:
SELECT <all fields you wish to post> FROM NEWS_TABLE WHERE NEWS_DATE = '$date_to_display';
This should give you the results of all the entries for a given date, as you want. Next would be to post them on your page. something like the following should work:
hope this helps, if you need more info feel free to post back.
