I've been working on implementing the iterator design pattern in PHP classes, but I'm a bit confused about how to handle it properly. I understand the basic concept of the iterator pattern, where it provides a way to access the elements of an object sequentially without exposing its underlying structure.
However, I'm unsure about the practical implementation. Could someone guide me on how to handle the iterator design pattern in PHP classes? I would really appreciate some code examples or step-by-step instructions on how to get started with it.
Thanks in advance!
