I get this error

Call to a member function get() on array

This my controller :

Function A
public function detailFees(){
$dataArray = array(
    'datapayment' => $datapayment,
    'countafter' => $countafter,
    'countbefore' => $countbefore
  );

}

I want to count just array data in datapayment with result in number

    You can’t use get() on an array because it is not a valid operation, and your detailFees() method does not accept any arguments because you did not define a parameter in the method.

    To count the array, you can do this:

    // Function B
public function data() {
    $dataArray = $this->detailFees();
    $datapayment = $dataArray['datapayment'];
    $dataCount = count($datapayment);


    return $dataCount;
}

    Inorder to make use of the get() method, convert the array as a collection using the collect() helper method.

    Function A:

    public function detailFees($key)
{
    $dataArray = collect(
        'datapayment' => $datapayment,
        'countafter' => $countafter,
        'countbefore' => $countbefore
    );

    $item = $dataArray->get($key);

    if (
        is_null($item)
        || ! is_array($item)
    ) {
        return 0;
    }

    return count($item);
}

    Function B:

    public function data()
{
    $data = $this->detailFees('datapayment');
}

    Actually, there are few ways to achieve your goal. The minimum cost is just returning $dataArray in function A

    public function detailFees( $market ){
    // .... your other codes
    $dataArray = array(
        'datapayment' => $datapayment,
        'countafter'  => $countafter,
        'countbefore' => $countbefore
    );
    return $dataArray; // add this line
}

    and then consume the returned array from function A to function B:

    public function data(){
    $data = count($this->detailFees($market)['datapayment']); // change this line
}

    simple without many changes.
