Just change the column in the ORDER BY:

Answer 2

Let MySQL handle the date stuff - IMO its MUCH better at it than PHP...

add a column with DATE or DATETIME type in your table. On inserting a new record either use NOW() or set a trigger to do it for you (will have to allow null in the coulmn if you are going to user a trigger)

your query should be:

$alist = mysql_query("SELECT * FROM articles ORDER BY `your_date_field` DESC");
