how can I get one return value of array in nested loop with conditional in php?

How can I get one return value array from if else condition ?

my code like this :

function fitur_4($extract_fitur){
    $fiturempat=array();
    $data_kata3=$extract_fitur['data_kata3'];
    $data_total_kalimat=$extract_fitur['data_total_kalimat'];
    $data_kalimat=$extract_fitur['data_kalimat'];
    for ($i=0; $i<count($data_kata3) ; $i++) { 
        for ($j=0; $j<$data_total_kalimat[$i]; $j++) { 
            $start='“';
            $kata=explode(" ", $data_kalimat[$i][$j]);
            $tot_kata=count($kata);
            $end ='”';
            $pos = stripos($data_kalimat[$i][$j], $start);
            $str = substr($data_kalimat[$i][$j], $pos);
            $str_two = substr($str, strlen($start));
            $second_pos = stripos($str_two, $end);//hitung per karakter
            $str_three = substr($str_two, 0, $second_pos);//kata dalam petik dua
            $unit = trim($str_three); // remove whitespaces
            $pecah_unit=explode(" ",$unit);
            $tot_petik=count($pecah_unit);

            if(strpos($data_kalimat[$i][$j], $start)!==false){
                $fitur4= $tot_petik/$tot_kata;
                array_push($fiturempat, $fitur4);                       
            }else{
                // empty value must insert in array $fiturempat
            }
        }
        return $fiturempat;
    }
}

I want to get return value $fiturempat in array from (if & else condition).
