How to store Birthdate and Age so that Age can be updated daily in PHP/MySQL?

Question

How should I store Birthdate\'s in MySQL so that I can easily update everyone\'s Age on a daily basis via a Cron Job?

Does it even make sense to sto

Answer 1

I don't think it's totally true that computing age dynamically takes a lot of memory. Why not create a table CALENDAR with 365 rows 1 row for each day of an year. And store a list of userid against the day corresponding to their birthday. For each day just refer the table entry for that day and refresh the age of only those selected users. This will reduce the complexity greatly even when the user base increases.
