Auto Calculate Total DAYS for leave, help please!

[Raffiq Eddy]

Dear MySQL & PHP Expert...

I want to auto calculate DAYS for leave taken based on date key-in by user:

For example:

Start date: 15-04-2004 -- (Friday)
End date: 18-04-2004 -- (Monday)
Days: 3 -- (calculate automatically)

From the date given above, system will automatically:-
1) Count days as 3 -- assuming working day is 15, 16 and 18 only.
2) Sunday will not be count as working day.

Is this possible with MySQL(3.32) + PHP ??

TIA,

Regards.
