php - 如何计算行和列中的值的总和？

Question

我有一个值表，其中填充了月份名称和总和的数组。如何计算行和列中这些值的总和并将结果显示在结果列的结果字符串中？

public function getReport($year=false)
    {           
        if (!empty($_GET['year'])) $year = (int)$_GET['year'];

        // собираем гигантский запрос
        $fields = 'all_months.fio, all_months.active_count AS sum_active_count, all_months.active_sum AS sum_active_sum';

        // результирующий запрос
        $data = array();
        // блок итого
        $data['result'] = array();

        // ставим ограничение по месяцу, если год текущий

        if ($year == (int)date('Y')) $max_month = date('m')-1;
        else $max_month = 11;

        foreach ($months as $key => $m)
        {

            // заголовки колонок запроса
            $data['months'][] = $m;
            $data['months_ru'][] = $months_ru[$key];

这段代码将进入您的 View 文件

'columns'=>array(
                ..........
                array(
                        'name'=>'age',
                        'footer'=>'Total: ' . $model->getTotal($model->search()->getData(), 'age'),
                ),
                array(
                        'name'=>'weight',
                        'footer'=>'Total: ' . $model->getTotal($model->search()->getData(), 'weight'),
                ),
                ..........
        ),

这个进入你的模型文件

 public function getTotal($records, $column)
        {
                $total = 0;
                foreach ($records as $record) {
                        $total += $record->$column;
                }
                return $total;
        }
