comparing two date

[odion121]

For this project i'm required to write a simple website. However, this web site must conform to a number of specifications.
You should create a simple home page for yourself. which i have done.
FIRST PROBLEM
This page should read an expiry date from an external file. If the current date is greater than the expiry date then a message to this affect should be displayed. The original page should also be displayed but with grey instead of black text.

You must also create an "administator's page" for your first page. This should be located in a secure directory accessible via a username and password. (I HAVE ALSO DONE THIS)

NEXT PROBLEM
This page is intended to "control" your first page. It should contain selection fields to reset the expiry date for the first page. Make sure that it is possible to set an expiry date in the past for testing purposes. When the administrator has chosen a new expiry date they will click an "update" button. This button will return a confimation page which will give details of the previous and new expiry dates.

how do i overcome this problem

There are plenty of date/time manipulation functions available, [man]date[/man], [man]time[/man], [man]mktime[/man], [man]strtotime[/man]; depending on your precise requirements, some combination of these (e.g., echo date('Y m d', strtotime('6 months'));).

Your problem is a bit too vague for a more specific answer (what is your problem?); perhaps if you explain just what it is you want help with.
