boolean isString(string)
boolean isNumber(number)
boolean validateStringForLength(string,length)
boolean validateNumberForRange(number,min,max)
boolean validateStringForCharacter(string,character)
These are the core of my base validation class. I'll often have more specific validation routines in an application specific validation class, these would often include validateEmail, validateSSN, etc, based on the needs of the application. Frequently, the methods in the application specific validation class use the methods of the base validation class.

That sounds good, could you give us some examples of the types of generic validation methods you have in the base class, are they things like email checking, length of strings etc?

I tend to have a validation method (or more often, several validation methods) which i can call when inserting, updating, etc.
Often, I create a base class with all my generic validation methods, which my other classes then inherit from.
