Cakephp using Set class to fetch data with key starting at zero - php

Question

I'm using Set class of Cakephp to format the find returned array but cannot seem to find a way to get the counter starting at zero and auto-increment for array keys so it is like
[0] => 3
[1] => 6
[2] => 12
I'm currently using below query to get the data from my HasAndBelongsToMany table.
$interest_ids = Set::combine($this->User->Interestsub->find('threaded', array
(
'conditions' => array
(
'Interestsub.name' => $interests
),
//'fields' => array('Interestsub.id'),
'recursive' => -1
)
),
'{n}.Interestsub.id',
'{n}.Interestsub.id'
);
The reason why I need this is that I'm currently trying to get the returned array as part of bigger parent array preparing to be saved for SaveAll function. To be formatted properly, I need below nested array coming out:
[0] => Array
(
[interestssub_id] => 12
[user_id] => 2
)
[1] => Array
(
[interestssub_id] => 22
[user_id] => 2
)
[2] => Array
(
[interestssub_id] => 32
[user_id] => 2
)
Is there a way we can use Combine class to format the returned array like above?

There's no real reason to use the Set class in this case. Just use good old fashioned php:
$threaded = $this->User->Interestsub->find('threaded', array(
'conditions' => array(
'Interestsub.name' => $interests
),
'recursive' => -1
));
$interest_ids = array();
foreach ($threaded as $thread) {
$interest_ids[] = array(
'interestssub_id' => $thread['Interestsub.id'],
'interestssub_id' => $thread['Interestsub.user_id']
);
}
