Php 表中列的总计

我想计算一个表中一系列列的总数，我该怎么做

下面是我想总结的数据示例：

array:1 [
  "traders" => array:6 [
    "Jim Mayor__targeted_target" => array:2 [
      "amounts" => array:13 [
        0 => 5
        1 => 5
        2 => 0
        3 => 0
        4 => 0
        5 => 0
        6 => 0
        7 => 0
        8 => 0
        9 => 0
        10 => 0
        11 => 0
      ]
      "row_name" => "Targeted target"
    ]
    "Jim Mayor__actual_targeted" => array:2 [
      "amounts" => array:13 [
        0 => 0
        1 => 1
        2 => 0
        3 => 0
        4 => 0
        5 => 0
        6 => 1
        7 => 1
        8 => 0
        9 => 0
        10 => 0
        11 => 0
      ]
      "row_name" => "Actual targeted"
    ]
    "Bob Martinez__targeted_target" => array:2 [
      "amounts" => array:13 [
        0 => 1
        1 => 0
        2 => 0
        3 => 0
        4 => 0
        5 => 0
        6 => 0
        7 => 0
        8 => 0
        9 => 0
        10 => 0
        11 => 0
      ]
      "row_name" => "Targeted target"
    ]
    "Bob Martinez__actual_targeted" => array:2 [
      "amounts" => array:13 [
        0 => 19
        1 => 45
        2 => 20
        3 => 26
        4 => 21
        5 => 10
        6 => 12
        7 => 20
        8 => 11
        9 => 2
        10 => 0
        11 => 0
      ]
      "row_name" => "Actual targeted"
    ]
...

我想将每个指数相加，例如，对于Jim Mayor_uuuTarget，指数0添加到Bob Martinez_uuuTarget的指数0中（这给出了1月份的总数）。它需要与数量不限的交易员合作

生成数据的函数：

protected function addRow($func, $params, $data, $year, $traderName, $rowName, $type, $image = null, $format = null, $underline = false)
    {
        $date = Carbon::createFromDate($year, 4, 1);
        $total = 0;
        $traderName = $traderName . '__' . str_replace(' ', '_', strtolower($rowName));
        for ($i = 1; $i < 13; $i++) {
            $params[1] = $date->year;
            $params[2] = $date->month;
            $result = call_user_func_array($func, $params);
            $data['traders'][$traderName]['amounts'][] = $result ? $result : 0;
            $total += $result;
            $date->addMonth();
        }
        $data['traders'][$traderName]['amounts'][] = $total;
        $data['traders'][$traderName]['row_name'] = $rowName;
        return $data;
    }

受保护的函数addRow（$func、$params、$data、$year、$traderName、$rowName、$type、$image=null、$format=null、$underline=false）
{
$date=Carbon:：createFromDate（$year，4，1）；
$total=0；
$traderName=$traderName.''.''.'.str'.'替换（'''.''.''.'strtolower（$rowName））；
对于（$i=1；$i<13；$i++）{
$params[1]=$date->year；
$params[2]=$date->month；
$result=调用用户函数数组（$func，$params）；
$data['traders'][$traderName]['amounts'][]=$result？$result:0；
$total+=$result；
$date->addMonth（）；
}
$data['traders'][$traderName]['amounts'][]=$total；
$data['traders'][$traderName]['row\u name']=$rowName；
返回$data；
}

只需检查数据并将结果保存在其他数组中：

$results = array();

foreach ($traders as $trader) {
    foreach ($trader['amounts'] as $i => $amount) {
        if (!isset($results[$i])) {
            $results[$i] = 0;
        }

        $results[$i] += $amount;
    }
}

结果数组将包含所有交易者的总和

未测试，但应能正常工作。

执行以下操作：

function sumRowsByMonth($traders)
{
    $sums = array_fill(0, 12, 0);
    foreach($traders as $trader) {
        foreach($trader['amounts'] as $monthId => $amount) {
            $sums[$monthId] += $amount;
        }
    }
    return $sums;
}

我用这个测试：

$arr = array(
    'traders' => array(
        'Jim Mayor__targeted_target' => array(
            'amounts' => array(
                0  => 5,
                1  => 5,
                2  => 0,
                3  => 0,
                4  => 0,
                5  => 0,
                6  => 0,
                7  => 0,
                8  => 0,
                9  => 0,
                10 => 0,
                11 => 0,
            )
        ),
        'Bob Martinez__targeted_target' => array(
            'amounts' => array(
                0  => 19,
                1  => 45,
                2  => 20,
                3  => 26,
                4  => 21,
                5  => 10,
                6  => 12,
                7  => 20,
                8  => 11,
                9  => 2,
                10 => 0,
                11 => 0,
            )
        ),
    ),
);
var_dump(sumRowsByMonth($arr['traders']));

使用函数

array\u sum（）

返回数组中的值之和

另外，您说过要分别计算

目标

和

实际目标

$actual = [];
$targeted = [];

foreach ($traders as $trader) {
    $sum = array_sum($trader['anmounts']);
    $trader['row_name'] === 'Actual targeted') ? $actual += $sum : $target += $sum;
}

也许您需要对此进行一点修改以调整行为，但我想我明白了。

我一直遇到的主要问题是，它将所有行相加，包括实际的行。实际的目标需要分组并分别汇总到目标

然后这样做：

function sumRowsByMonth($traders)
{
    $sums = array();

    foreach($traders as $traderName => $trader) {
        $type = strstr($traderName, '__');
        if( empty($sums[$type]) ) {
            $sums[$type] = array_fill(0, 12, 0);
        }

        foreach($trader['amounts'] as $monthId => $amount) {
            $sums[$type][$monthId] += $amount;
        }
    }
    return $sums;
}

我一直遇到的主要问题是，它将所有行相加，包括实际值。实际目标需要分组并分别汇总到目标目标。我使用strstr发送了另一个答案。谢谢，但问题是名称也是动态的，所以“实际目标”可以是任何内容。@imperium2335向数组添加一些静态标志。
