How to write models

[eluser]papagno[/eluser]
Yes, I think that the ORM approach is what I need, but it's a library really necessary for this task?


EDIT: I'm trying DataMapper now and I think it's weird that to get (for example) all my posts I have to instantiate a Post and then call a method on the instance:

Code:

$post = new Post();
$posts = $post->get();

Do you know of any other library that use a different approach with ORM?


EDIT 2: I did a print_r of the $posts variable (2 rows with 3 attributes) and I got 1291 lines (within a pre tag)! Is that normal?
