I am getting a date field from the database in one of my variables, at the moment I am using the following code to check if the date is in “yyyy-mm-dd” format
if ( $dat =~ /\d{3,}-\d\d-\d\d/ )
My question, is there a better way to accomplish this.
Many Thanks
As noted by others, if this is a date field from a database, it should be coming in a well-defined format, so you can use a simple regex, such as that given by toolkit.
But that has the disadvantage that it will accept invalid dates, such as 2009-02-30. Again, if you’re handling dates that successfully made it into a date-typed field in a DB, you should be safe.
A more robust approach would be to use one of the many Date/Time modules from CPAN. Probably Date::Manip would be a good choice, and in particular check out the ParseDate() function.
