My opinion: Private class properties are prefixed with '_' due to PHP which has no real private class members. If I want to make public property (I will never, but if yes), I don't prefix it. > Class DB is a class with static methods only, and the two most important > ones (factory and connect) either return an object of the requested type, > or an instance of class 'PEAR_Error'.

You can make you own error handler via callback function and there recognize according to production state what to do with occured error. =Nepto= ____________________________________________________________________________ Ondrej 'Nepto' Jombik, http://www.nepto.sk/ nepto@atomicpile.sk
