change database value with cron php |

Is it possible to check a mysql database value once a day with a cron job and using php change it if true?
Basically when someone enters an item into the database it is assigned a 'type' value of '1' (items are usually listed for 12 months).
The user of the item may make it 'Featured' at any time for 1 month or 3 months, which assigns it a 'type' value of '2'.
Once the 1 or 3 month 'Featured' is over I want to convert the 'type' value back to 1 in the database but at the moment it is staying at '2'.
I would like to run a cron job - once a day to check that if the 'Featured date end' is less than today - change 'type' value back to '1'.
Would I get the cron job to run some kind of php script to change the value?
Any help appreciated!

Well, I'd do it in perl, but yeah, you should be able to set up a daily cron for that. :-)
First disable your 12 month ones.

update table set type=0 where approved=1 and date_add(posted_date, interval 12 month) <= curdate();
in the same script, now run the second command.

Even easier would be a cron job running a mysql script:
#dailyupdate.sh
mysql --user=yourdatabaseuser --password=yourpassword <dailyupdate.sql
create dailyupdate.sql from rocknbill's example above.
#dailyupdate.sql
update table set type=1 where approved=1 and featured_date_end <= curdate();
Now set up a cron job to run dailyupdate.sh just before / after midnight or so.
