Its a fairly stright forward question I think.
Lets say I have an Enum or a Set type, where I specify the specific values of the Set. Say the field is called Fruits. If I want to have more different types of Fruits available later, I can edit and add those new fruits to the set type later. So lets say for right now I have Apples, Oranges, and Bananas. In my php code, I could hard set these values, but I want to count the total number of different values, or simply return the values themselves. I'll be happy with either an INT for returning a COUNT(*) or the Value, IE mysql_fetch returns (Apples, Oranges, Bananas), so either way. The total number probably isn't going to be a very high number, single digits, maybe low double digits...
How on earth would I do that?
