Thread: Looking for a user expires @ date

Looking for a user expires at date

My idea is

1. user a (
wil be expire - example 01/01/2013 - script must send a email to this person automatic 3 times
- 3 weeks before
- 2 weeks before
- 1 day before
2. user b
3. user c
4. user d
5. user e
6. user f
7. user g
8. user h
9. user i
10. user j

So the base of this example, we have a user+date this list i have made allready

example:
1: linuxbuddy1
1: 01-01-2013
1: emailadress 1(example)
2: linuxbuddy2
2: 01-01-2013
2: emailadress2 (example)
3: linuxbuddy3
3: 01-01-2013
3: emailadress3 (example)
4: linuxbuddy4
4: 01-01-2013
4: emailadress4 (example)


The email must be send also to a emailadress webmaster

I hope i this is the info you all need who/want can/to help?

The script must check the dates en send a alert

This script looks a lot to the final, but don't have any idea
