Question

我们能算出来自foreach的具体价值吗？例如：

--total--
2
3
4
--total 2--
5
6
7

总计应为：9

总计2 承担：18

这是我的观点：

<table class="table table-bordered">
<thead>
    <tr>
        <th rowspan="2">Kode</th>
        <th rowspan="2">Uraian</th>
         <th colspan="3">Rincian Perhitungan</th>
        <th rowspan="2">Jumlah</th>
        <th rowspan="2"></th>
    </tr>
    <tr>
        <th>Volume</th>
        <th>Satuan</th>
        <th>Harga Satuan</th>
    </tr>

这是我的控制器

function detail_belanja($id){
    $this->load->model('kegiatans');

    $belanja =  $this->kegiatans->get_belanja($id);
    foreach ($belanja as $key => $v) {
        $hasil[$v->kd_rek_1_gab][$v->kd_rek_2_gab][$v->kd_rek_3_gab][$v->kd_rek_4_gab][$v->kd_rek_5_gab][$v->kelompok_id.'|'.$v->kelompok][] = $v;
    }
    $data['belanja'] = $hasil;
    echo '<pre>';
    var_dump($data['belanja']);
    echo '</pre>';
    $this->load->view("bidang/belanja_list",$data);

在你的情况下，如果你想使用foreach循环，那么：

$sum = 0;
foreach($group as $key => $value) {
   $sum += $value; 
}
echo $sum;

但是如果你想使用数组的直接总和而不是下面的解决方案：

$total = array_sum($group);
