Answer 1

I would'nt do this with PHP. A database should know, what day is today.( use MySQL->NOW() for example ), so it will be very easy to compare within the Query and return the result, without any problems depending on the used Date-Types

SELECT IF(expireDate < NOW(),TRUE,FALSE) as isExpired FROM tableName
