Can you be a little more specific/descriptive?

There is a brief introduction on:

i need to create a collection class with students,(add/delete,etc) but it must be using the "collection class" concept.

You'll probably want your collection implement Iterator and Countable.

(http://us3.php.net/Countable)

(http://us3.php.net/manual/en/class.iterator.php)

 

However, there's more than one way to skin a cat. There's all sorts of different types of collections you could implement: stacks, queues, linked lists, trees, etc.. I use collections on my blog, here's an example:

 

The abstract class, which implements Iterator and Countable:

A class which extends the above class:

The class which acts as items in the above collection:

Hope this helps.

You can always refer to one of the SPL data structures:

it has to be a custom generic collection class and not any of the predefined ones(queue,stack) etc.
