[PHP] Date Validation, Kinda'

[Jay Blanchard]

[snip]
Now that I'm thinking about it, what is your goal with this? Is it to
make sure the date entered is within a certain range when compared to
another date? i.e. The date entered cannot be more than absolutevalue(10
days) away from the first date or is it just to make sure it's in the
proper format?

It is to make sure that the user has entered a valid future date in the
YYYYMMDD format into the form.

I'm thinking this:

1. you get the date from the user
2. validate it using checkdate()
3. get the current date
4. compare the two dates to see if the users date is later than todays
date
5. return true or return false

Sound good?

Sounds bueno! I am just tired, had checkdate() in hand...Thanks!
