如何在Php中更改关联数组的数组结构

Question

I want to change my array from, how can i make this kind of a change.

Array ( [0] => 53720 [1] => Array( ['Build Quality'] => 1=>10, 2=>9, 3=>7 ['Versatality'] => 1=>9, 2=>8, 3=>7 ['value'] => 1=>8, 2=>6, 3=>5 ) );

to:

Array ( 53720 =>['Build Quality' => [1=>10, 2=>9, 3=>7], 'Versatality' => [1=>9, 2=>8, 3=>7], 'value' => [1=>8, 2=>6, 3=>5] ] );

function get_array(){

  $factor = array([0] => 'Build Quality' [1] => 'Versatality' [2] => 'Value');  
  $rank = array([0] => 1=>10,2=>9,3=>7 [1] => 1=>9,2=>8,3=>7 [2] => 1=>8,2=>6,3=>5);  
  $assoc_array = array_combine($factor, $rank);
  $post_id = get_current_post_id(); //gives 53720   
  $result = array();
  array_push($result, $post_id, $assoc_array);  
  print_r($result);  
  return $result[$post_id];

/* output: Array ([0] => 53720 [1] => Array (['Build Quality'] => 1=>10,2=>9,3=>7 ['Versatality'] => 1=>9,2=>8,3=>7 ['Value'] => 1=>8,2=>6,3=>5)) */ 
}

You can add elements to an associative array directly:

$result = [];
$result[$post_id] = $assoc_array;

You can also initiate one with keys and values directly:

$result = [
    $post_id => $assoc_array
];

Also keep in mind that not any variable can be used as a key, as stated in the PHP documentation for arrays :

The key can either be an integer or a string. The value can be of any type.
