This is not session module specific, your interface is specifying a return type. Thus this should be enforced on the interface implementation level. (I.e. it will be impossible for an user to define a function not having a return type of string/array) Also, if a wrong argument is passed to a function, it should throw a type error. Perhaps old modules from pre-PHP 5 do emit warnings or recoverables, but we then shall transition from that to TypeError, and definitely use TypeError in new functionality. Bob
