Как суммировать значения массива того же ключа и сохранить его в базе данных? Я застрял в процессе выполнения foreach для результата Я пытался использовать для каждого из них, но не могу получить нужный результат, который мне нужен

Answer 1

Используйте вложенный оператор foreach и создайте массив с теми же ключами , Для ех,

$temp = array(); 
foreach($main_array as $key=>$val){ 
    foreach ($val as $key2=>$val2) { 
     if(!isset($temp[$key2])) 
      $temp[$key2]=0; 
     $temp[$key2]+= $val2; 
    } 
} 
//$temp will hold a row of same keys sum
