Question

有这样的数组：

    array (
  '@attributes' => 
  array (
    'status' => 'ok',
  ),
  'time_entries' => 
  array (
    '@attributes' => 
    array (
      'page' => '1',
      'per_page' => '100',
      'pages' => '1',
      'total' => '33',
    ),
    'time_entry' => 
    array (
      0 => 
      array (
        'time_entry_id' => '1411884',
        'staff_id' => '22384',
        'project_id' => '11116',
        'task_id' => '3296',
        'hours' => '1.75',
        'date' => '2017-02-20',
        'notes' => 'What is Quadra, Events Slider, Event Page Setup',
        'billed' => '0',
      ),
      1 => 
      array (
        'time_entry_id' => '1411254',
        'staff_id' => '22384',
        'project_id' => '11116',
        'task_id' => '3296',
        'hours' => '1.5',
        'date' => '2017-02-17',
        'notes' => 'Events Slider, Background overlay, Intro',
        'billed' => '0',
      ),
      2 => 
      array (
        'time_entry_id' => '1410694',
        'staff_id' => '22384',
        'project_id' => '11116',
        'task_id' => '3296',
        'hours' => '2.75',
        'date' => '2017-02-16',
        'notes' => 'Background Image SVGs, Header, Footer',
        'billed' => '0',
      ),
      3 => 
      array (
        'time_entry_id' => '1410586',
        'staff_id' => '22384',
        'project_id' => '11116',
        'task_id' => '3296',
        'hours' => '0.5',
        'date' => '2017-02-15',
        'notes' => 'Site Background 
Assign Less Variables',
        'billed' => '0',
      ),
      4 => 
      array (
        'time_entry_id' => '1409621',
        'staff_id' => '22384',
        'project_id' => '11116',
        'task_id' => '3296',
        'hours' => '0.25',
        'date' => '2017-02-14',
        'notes' => 'Theme Install',
        'billed' => '0',
      ),

...它实际上比第一个更进一步4.我要做的是通过键[“task_id”]对这些数组进行排序，以便我可以将它们组合在一起，然后将[“小时”加在一起“]键 - 这样我最终可以输出每个task_id下的总工作小时数。

我尝试了一些'array_merge_recursive'和类似但我不知所措;这是PHP比我的水平高一点。非常感谢。

Answer 1

因此，通过生成一组新数据而不是尝试修改此数组，您可能最好通过总和进行求和。

这样的东西会给你你想要的东西：

$time_entries = $your_array["time_entries"]["time_entry"];
$task_hours = [];
foreach ($time_entries as $time_entry) {
    if (!isset($task_hours[$time_entry["task_id"]])) {
        $task_hours[$time_entry["task_id"]] = 0;
    }
    $task_hours[$time_entry["task_id"]] += (float) $time_entry["hours"];
}

$task_hours会给你一个像：

的值

Array
(
    [3296] => 5
    [1879] => 0.25
)

Answer 2

而不是对数组进行排序，然后总结小时，以便不处理该数组的相关部分并一次性完成求和。

ConstraintLayout

您现在应该有一个数组，其中键是$tots = array(); foreach( $array['time_entry'] as $task ) { if ( isset($tots['task_id']) ) { $tots['task_id'] += $task['hours']; } else { $tots['task_id'] = $task['hours']; } }，其值是所有键task_id的总和。

如果您想按顺序排列hours，那么在输出任何结果之前对task_id数组进行排序

$tots

如果您希望结果按照小时数的顺序

ksort($tots);
