[development] Drupal - to use objects or arrays

I think the general guideline is "use what makes semantic sense at the time".
A single entity is an object. (Eg, nodes, users, etc.) A list of things is
an array. A list of entities is an array of objects.
When you get into really complex data structures, like FAPI, then I think
deeply-nested arrays are easier to work with and more predictable (esp.
between PHP 4 and PHP 5) than deeply-nested objects. You can have an object
one of whose properties is a complex nested array (Nodes created with CCK,
esp. in Drupal 5, do that).
There's no hard rule, but I think "what makes semantic sense when writing it"
is the guideline. Oh yes, and when iterating over records from a database
where it really doesn't make a difference, using db_fetch_object() seems more
common than db_fetch_array(), simply because there's fewer funky characters
involved with objects than arrays. :-)

"If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an idea,
which an individual may exclusively possess as long as he keeps it to
himself; but the moment it is divulged, it forces itself into the possession
of every one, and the receiver cannot dispossess himself of it." -- Thomas
