如何对CakePHP多维数组进行排序？

Question

Find statements in CakePHP produce an array structured as below. I've already ordered my search to produce the result set shown (ordered by combined_score). Now, I'd like to apply a sorting function on the data to sort by "average_votes". See "from this:"/"to this:" below.

I'd really appreciate any suggestions.

From this:
Array
(
[0] => Array
    (
        [Vehicle] => Array
            (
                [id] => 52
                [user_id] => 101
                [name] => Ford
                [total_votes] => 5
                [average_votes] => 3.8
                [combined_score] => 19
            )

    )

[1] => Array
    (
        [Vehicle] => Array
            (
                [id] => 48
                [user_id] => 101
                [name] => Nissan
                [total_votes] => 6
                [average_votes] => 5
                [combined_score] => 2
            )
    )
)

To this:
Array
(
[0] => Array
    (
        [Vehicle] => Array
            (
                [id] => 48
                [user_id] => 101
                [name] => Nissan
                [total_votes] => 6
                [average_votes] => 5
                [combined_score] => 2
            )
    )   

[1] => Array
    (
        [Vehicle] => Array
            (
                [id] => 52
                [user_id] => 101
                [name] => Ford
                [total_votes] => 5
                [average_votes] => 3.8
                [combined_score] => 19
            )

    )

)

Answer 1

Depending on what you're actually trying to achieve you can still do this at the database level in cake, like so:

$this->Vehicle->find('all',array('order' => array('Vehicle.combined_score' => 'asc', 'Vehicle.average_votes' => 'desc')));

Which will first sort by combined score, and then sort by average votes

The second option is to use the cakephp Set class, like so:

$results = Set::sort($results, '{n}.Vehicle.average_votes', 'desc');
