For some reason, dates and databases seem to cause problems for many people.
Yes, you should certainly rtfm, there are many functions in php and
mysql/postgresql that deal with functions and they may clarify your problem.
Then again, they may not.
The basic problem that most people run into is that they attempt to compare
dates that are in different formats. Just because your database dates and
php date are both integers does not mean they are in the same format. One
could easily be formatted MMDDYYYY while the other is formatted YYDDMM.
Obviously you will not get the desired results if you attempt to compare
dates in different formats.
My first suggestion would be to use the date data type instead of an
integer. There are all kinds of built in funtions for dealing with dates in
the date format. If you must use integers for some reason use the unix time
stamp because there are also functions for dealing with that date/time
format. If you have no control over the way data is stored in the database,
take a good look at the actual data and make sure that your php date is
formatted exactly like your database dates.
If you are going to stick with integer dates then you do not use the quotes
around the variable, as they are used for strings and not numbers.
