如何遍历非结构化的多维数组

Question

我遇到来自Web服务的SOAP响应问题。 响应是一个多维数组，每个员工的结构不同。

我尝试使用foreach循环来检索所有值并将它们存储在mysql数据库中。

Array
(
    [item] => Array
        (
            [0] => Array
                (
                    [department_id] => 1
                    [department_name] => Sales
                    [department_shortname] => SA
                    [hours] => Array
                        (

我试过这个，但我没有得到所有的数据。

foreach($array as $employees)
{
  foreach($employees as $employee)
  {
    foreach($employee as $days)
    {
        foreach($days as $day)
        {
          foreach($day as $item)
          {
            foreach($item as $stores)
            {
              foreach($stores as $store)
              {
                foreach($store as $item1)
                {
                  foreach($item1 as $item2)
                  {
                    foreach($item2 as $hours)
                    {
                      foreach($hours as $hour)
                      {
                        foreach($hour as $booking)
                        {
                          /*
                          Store in DB per time registration.

                          $hours['department_id']
                          $hours['department_name']
                          $hours['department_shortname']

                          $booking[activity_id]
                          $booking[start_date]
                          $booking[end_date]
                          $booking[start_time]
                          $booking[end_time]
                          $booking[hour_code]
                          $booking[foreign_hour_code]
                          $booking[amount]
                          $booking[type]
                          $booking[labor_cost]
                          */
                        }
                      }
                    }
                  }
                }
              }
            }
          }
        }
    }
  }
}

我希望循环遍历所有元素，并在每次注册时将它们存储在数据库中。

department_id | department_name | department_shortname | activity_id | start_date | 结束日期| start_time | end_time | hour_code | foreign_hour_code | 金额| 类型| 劳动力成本

Answer 1

我将通过查看“项目”来开始这个答案。 值得注意的是，当'items'中只有1个项目时，它就在那里，但是如果有多个项目，则使用数字项目数组。 因此，让我们为此制定一些功能，只是为了纠正这种不一致。

function getItems($itemArray)
{
  // get the items in the item array
  $items = $itemArray['item'];
  // multiple items, in a numeric array, are returned as they are
  if (array_keys($items) === range(0, count($items) - 1) return $items;
  // whereas a single items is placed in a numeric array
  return [$items];
}

我们可以将此应用于任何“项目”。

现在我有一个问题，因为你没有给我足够的信息。 我不知道你给我看的两个阵列是什么的一部分。 所以我将不得不假设你可以得到它们。 它们是物品。 让我们给他们一个名字：'startpoint'。 这是选择相当abitrary。

function processStartpoint($startpoint)
{
    // first get the department items
    $departments = getItems($startpoint);
    // process each department
    foreach ($departments as $department) {
        // get department info
        $departmentId        = $department['department_id'];
        $departmentName      = $department['department_name'];
        $departmentShortName = $department['department_shortname'];  
        // walk through each hour
        foreach (getItems($department['hours']) as $hour) {
            // get hour info
            $ActivityId      = $hour['activity_id'];
            $StartDate       = $hour['start_date']; 
            $EndDate         = $hour['end_date']; 
            $StartTime       = $hour['start_time']; 
            $EndTime         = $hour['end_time'];
            $HourCode        = $hour['hour_code']; 
            $ForeignHourCode = $hour['foreign_hour_code']; 
            $Amount          = $hour['amount'];
            $Type            = $hour['type'];
            $LaborCost       = $hour['labor_cost']; 
            /*
              store this in your database
            */
        }
    }
}

现在我没有真正的方法来检查这段代码是否有效，但是这样的话会有。 真正的技巧是在getItems()函数中，它对数组的结构作出反应。
