Structs and sets

Two short questions:

1. Is there any implementation of sets in PHP4?
2. Can I define structs (e.g., as in C++) or do I have to use classes
instead??

Cheers,
Matthias

What exaclty do you mean with Sets ?

What is the difference between structs an classes ? Just the default
access (structs: public classes: private)
You should use classes as in C++, but you have no differences or
mechanism to distinguish between private and public elements (only
in PHP5).

Kind Regards

If "Sets" means Enumerations, then no, there are none in PHP. You
could maybe fake it with a class that has an array of allowed options.

No, but PHP arrays are flexible enough to emulate them.

You can do that, if you want...

That's what I meant.
