If you're going to do that, then I suspect that you have at least 365 jokes. If that's the case, then just use the data(z) function to pull of the joke who's id is the same as the day of the year.

Hi Delta,
You haven't stated whether you want the database retrieval to be
random (although constant for one day) or sequential. If sequential,
I'd think you could just use the day number as an offset into the recordset:
SELECT Joke FROM Jokes LIMIT $iDay, 1
where $iDay is the current offset of today in the year -- in PHP
that's date('z').
http://php.net/date
All you'd need is 356 jokes to guarantee a different one each day.
However, it sounds like you want the joke to be extracted at random
each day. I'd like to question this approach, as it will undoubtedly
output some of the same jokes more than once in a given year...
unless you build in a way of preventing duplicates... or unless your
client doesn't care if that happens...
What I would suggest is to allow the software to extract jokes
sequentially using "LIMIT $iDay, 1" and generate the database of
jokes, in whatever order, once a year. Rather than randomly
selecting a record each time you pull a joke from the database, you
apply any randomness you want once a year when the database is assembled.
Regards,
Paul

Thanks in advance :) I would write the query results to a php file as string variables and when someone requests the page have a date conditional to decide which string to display. Or if you want to pull a joke from the database one at a time just use date to determine which one. For this you may have to have a persistent php file to include to keep track. Ideas; maybe one looks good? Best Jeff k -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi,
again me with the silly questions...
you could have another table in your database that logs the id of the
current joke and the date it was shown on, then simply 'select
jokeid,dateshown from jokelog order by dateshown limit 1' will get you
the last joke and when it was used, if the date is yesterdays date then
get a new joke from the joke table.
you could also have do the same but store 1 entry in a file, file io is
sometimes quicker than a query on a large db.
