How to check specific index of value is exist

-3

I have a php array like this.

Array

(

    [first_year] => Array

        (

            [1] => Array

                (

                    [0] => Array

                        (

                            [distiction] =>  , 2, 3, 4, 5, 6,  , 8, 9

                            [name] => ‌Mark

                            [status] => Pass with credit

                        )



                )



            [2] => Array

                (

                    [0] => Array

                        (

                            [distiction] =>  , 2, 3, 4, 5, 6, 7,  , 9

                            [name] => ‌John

                            [status] => 

                        )



                )



        )

)

I got that data by print_r($dataArray[$academic_year][$major]).
How can I check if $dataArray[$academic_year][$major][$year] and check if [first_year] has values or not? I have already tried out empty(), !array_filter() and $dataArray[$academic_year][$major][$year] == .
But none of it working for me. Thank you.

You can use:

if (array_key_exists($year, $dataArray[$academic_year][$major])) {

    if ($dataArray[$academic_year][$major][$year]){

        //your code here

    }

}

Just return default behavior when it does not exist:

$data = $dataArray[$academic_year][$major][$year] 

        ?? ['distiction' => '', 'name' => '', 'status' => ''];

$data = $dataArray[$academic_year][$major][$year] ?? null;

if (is_array($data) && !empty($data)) {

  // Your code...
