Assuming you know how to create a MySQL db and the proper lines to query
it from within PHP I'd go for a db setup like this:
Fields:
- MsgID Holds the unique message number
- Message The actual message string.
- OptYes A string with the numbers of the next messages to display e.g
"2,6,7"
- OptNo A string with the numbers of the next messages to display e.g
"9,11,21,27"
Of course you have to make sure people can't run in circles and always
end up somewhere definitive. If your desing is good loops should not
occur, if you want a safety valve you could include a field
"HasBeenUsed" with a TRUE or FALSE option.
If you want the system to adapt itself (more advanced) you could tally
the number of times a certain option was chosen and in the future list
those first. Keep score in another field of course.
I am sure there are a zillion ways to do this, and better at that. But
here's one!
Success
