Helo there, im trying to figure out how to write a function that returns a multidimensional array, based on the data below:

I know how to write the function using the "category_parent" value, but im just trying to write a function that can create a multidimensional array by JUST using the left and right keys.

Any help greatly appreciated!

array(71) {
  [0]=>
  array(9) {
    ["id"]=>
    string(1) "1"
    ["category_name"]=>
    string(6) "Rubros"
    ["category_parent"]=>
    string(1) "0"
    ["category_slug"]=>
    string(6) "rubros"
    ["category_image"]=>
    NULL
    ["category_totals"]=>
    NULL
    ["category_lft"]=>
    string(1) "1"
    ["category_rgt"]=>
    string(3) "142"
