Thanks for the reminder :) I thought about that at the first source of the problem, but: It works with php4. For instance this is widely used to include a given file on demand, and only on demand. I thought that in the context of getFoo (lost between 2 calls), it should include it again. In this simple case, it is not a problem, there is no global "pollution". But in the case the included files contains a class/function definition, you run in troubles. That's why I think the behavioir should remain the same as with php4. An alternative is to split all possible runtime datas to a different file and not in the same file as the class/function declaration. But in both cases that will break a lot of scripts around. hth pierre
