Question

我一直在搜索并且找不到它，尽管很难用语言表达，所以如果它在其他地方被提及，我深表歉意。

我进行了一个API调用，这给了我。这是在给定日期工作的班次，每个班次都有一个数组。这就是样子。

$lastMon = array{
       date => $date
       hours => 8
       worker => mjones
       etc
       }

现在，我想获取招聘者的价值和小时数，并创建另一个看起来像这样的数组

$lastMonData = array{
       key for each $lastMon->recruiter => sum of all $lastMon->hours where recruiter is unique
       total += $lastMon->hours
       }

基本上，我从该系统中提取了一堆班次，并将其转变为数组，并插入了从系统其他部分提取的一些键。然后，我需要一个按日期排列的数组，其中包含当天所有班次的总工作时间，然后是招聘人员密钥中每个唯一名称的密钥，该密钥将同一阵列中提到的工时加起来。我希望这是有道理的。

    [lt_orderID] => 0
    [dateTimeModified] => 2018-08-20T10:05:33
    [recruiter] => Mike Jones
    [hours] => 04
)

我需要获取招聘者的价值，并将这些价值放入新数组中的键中。重复一些，所以我只想选择独特的。然后，该数组中的小时数将是新数组中招聘人员姓名键的值。

所以这看起来像

$lastMon = array{
      Mike Jones => 4
      John Smith => 5
      Total => 9
}

您可以使用array-reduce来汇总招聘人员的时间：

$lastMon = array(array("recruiter" => "AAA", "hours" => 4), array("recruiter" => "BBB", "hours" => 5), array("recruiter" => "AAA", "hours" => 3));

function reduceHours($carry, $item)
{
    if (!array_key_exists($item["recruiter"], $carry))
        $carry[$item["recruiter"]] = 0;
    $carry[$item["recruiter"]] += $item["hours"];
    return $carry;
}


$lastMonData = array_reduce($lastMon, "reduceHours", array());

这将输出：

Array
(
    [AAA] => 7
    [BBB] => 5
)

现在您添加了更多数据，我可以为您提供更详细的答案：

$str = '<xml><shifts><recruiter>John Smith</recruiter><hours>05</hours></shifts><shifts><recruiter>Mike Jones</recruiter><hours>04</hours></shifts><shifts><recruiter>John Smith</recruiter><hours>08</hours></shifts></xml>';
$arr = json_decode(json_encode((array) simplexml_load_string($str)), 1);

function sum($carry, $item) { return $carry + $item;}
function reduceHours($carry, $item)
{
    if (!array_key_exists($item["recruiter"], $carry))
        $carry[$item["recruiter"]] = 0;
    $carry[$item["recruiter"]] += $item["hours"];
    return $carry;
}

$lastMonData = array_reduce($arr["shifts"], "reduceHours", array());
$lastMonData["total"] = array_reduce($lastMonData, "sum");

将xml对象转换为数组来自here。

这将为$lastMonData提供输出：

Array
(
    [John Smith] => 13
    [Mike Jones] => 4
    [total] => 17
)

我知道总数的总和可以用其他方法完成，但我尝试保留使用array_reduce的示例。

从另一个数组值创建一个数组
