By using partial classes those can be in different files, thus developers don't touch generated files. Except for that a need for splitting this up indicates a design issue to me. Like a class doing too many things. PHP has traits which you eventually can use to emulate such a system in a more explicit way. http://php.net/traits > Q: What will happen if both classes contain same method names? > A: We will show error method already exists. > > Q: Will it break any existing code? > A: No, there will be no impact on any existing coding because we are > not changing anything. It would break usage of "partial" which is not a keywor, yet. johannes
