If you are inputting the date directly into the database, then simply use
in place of a variable.
for example for an insert statement:
Code:
INSERT INTO forum (id,date,whatever) VALUES ('1', NOW(), 'whatever');
For an update statement:
Code:
UPDATE forum SET id = '1', date = NOW(), whatever = 'whatever' WHERE id = '1';
then simply write your script in PHP to translate the date / time stamp into a more asthetic view.
What format MySQL uses will be determined by the column type. i.e. a 'DATE' type will only give today's date, whereas a datetime type will give a hash comprised of the date, and current time down to the second.
