I've got about 2 mins to answer your question, so let me just point you in the right direction! PHP has some handy date functions for manipulating the date field in mysql.

The one that probably interests you is date() which allows you to format a date to display in any way you want.
However, there are several ways to store a date in MySQL, so ensure that you're using the method that suits your application best. If in doubt, head over to http://dev.mysql.com/doc/mysql/en/Da..._overview.html

If you're still having trouble when I get back then let me know and I'll try to help some more.
