Thanks for your replies.
I understand the differences between the 2 types of array.
I only asked why when I add another key and end up with array(4=>$a,
12=>$b), NOW the Set::extract is working as normal.
As for the combination of extract and combine, I believe there could
be situations where it's useful.
In my case, I take the result of my find and combine the array in a
way that I can group data of the same type together.
This allow me to do a simple foreach on every type possible (they can
vary) and compute stats for each of them based on their data.
There are surely other ways to do it, but depending on different
factors, this is the quickest and cleanest I've found.
So this result of find
Array
(
[0] => Array
(
[data] => Array
(
[some data] => some value
[type] => type1
)
)
...
)
Become
Array
(
[type1] => Array
(
[4] => Array
(
[data] => Array
(
[some data] => some value
[type] => type1
)
...
)
[12] ...
)
[type2] ...
)
Obviously, this is based on the possibility to do an extract on any
type of array, which is not the case, and that's what led me to my
final question on the combine.
But as I see your last answer, I suppose that it's not possible to
combine with default numeric keys.
I'll do a simple foreach.
