仅从一个php函数返回多个值

Question

我有一个包含一些数据的大型数组。我试图只做一个函数来返回每个值的总和，从月份的乞讨到每个月的月末。我创建了一个函数，返回一个“键”的总和，但我必须为每个键重复我的自我。是否可以只使用一个函数进行多次返回，例如将它们放入数组中？

//I'am using this function for returnig the value
function kontratat_tot_grupi($date,$grup_name,$value){
    $tot_grupi = $date[$grup_name][$value];
    return $tot_grupi;
}

//and here i'am using the function on grup_a in a while loop
$tot_grup_a += kontratat_tot_grupi($date,"grup_a","luce");


//this is a piece from my array
