Another great tutorial Harry, thanks!

Here's a way to do the Observer pattern without multiple inheritance:

http://blogs.teamb.com/joannacarter/articles/690.aspx (Note, this is an article on Delphi, not PHP, but the ideas translate because we have interfaces now in PHP5)

Good article

Would be nice to adapt the Eclipse library to use SPL. DatabaseIterator is something I want to use...

Great write up Harry! I'd love to see more about Iterators!!

Big Fat Bob · Sep 13, 2004, 12:02

Yo Doug,

Thanks for the link, have now added it to my favourites

Btw, there is another link at this blog on Iterators, apparently both articles were written for a future book.

Just wish SPL was more integrated with the rest of PHP.

Both SQLiteResult and SQLiteUnbuffered do not implement the Iterator interface. So can not pass them to function with type-checking, like a subclass of FilterIterator. Even thou can use foreach() on both. So have roll a wrapper to get interface.

Similarly DOMList seems suitable for an ArrayAccess interface.

Well.. PHP is open source!

I do agree with your point though, SPL is underused atm. I'd like to see more done with it than just Iterators, though even just that is nice

I've got my QueryIterator working too

Cool article Harry; I knew about Iterator and IteratorAggregate, but not the others.

I can just see inexperienced scripters getting seriously confused though;
when they see an object being accessed with an array syntax, only to try it themselves and not being able to get it to work.

Accessing objects as arrays can be a little confusing. Except if you use Delphi!

contents of a container can be accessed as an array.

Form.StringList.Items[2] (I think is) the same as Form.StringList.Items.GetItem(2)

The '.' in Delphi is the same as '->' in PHP.

I like the idea, but my lack of experience confuses me with knowing when I should use them.

I want container/component classes. (Table/Columns).

ADOdb already has it -- you can foreach an ADORecordSet object with PHP5.

a good article.Thanks

Yeah iterators aren't such a huge deal in my opinion.

In C# I had to use them for the MCPD cert. tests and also use object indexers and all that stuff... But I never seen myself actually choosing to work with them. I don't see a necessity for them in any common case.
