Question

Fund few functions to sort array but none of them can sort them if they are stdClass Object or ad least I could not find the right one

I need to sort this array by ordering value

 [data] => Array
                (
                    [0] => stdClass Object
                        (
                            [id] => 12
                            [name] => Title1
                            [ordering] => 1
                        )

                    [1] => stdClass Object
                        (
                            [id] => 14
                            [name] => Title2
                            [ordering] => 3
                        )

                    [2] => stdClass Object
                        (
                            [id] => 18
                            [name] => Title4
                            [ordering] => 2
                        )

                    [3] => stdClass Object
                        (
                            [id] => 22
                            [name] => Title5
                            [ordering] => 4
                        )

                )

any help is appreciated. Thank you!

Answer 1

Define a custom sorting function based on ordering field of your objects, then pass it in with usort.

docs for usort

function sortByOrdering($obj1, $obj2) {
   return $obj2->ordering - $obj1->ordering;
}

usort($input['data'], 'sortByOrdering');

Note that you don’t need to reassign $input = usort(...) as the array is referenced inside usort
