用于谷歌图表的 PHP 数组； 循环遍历数组并按 2 分组

Question

（在圣诞大餐之间）我再次陷入数组和逻辑分组的循环中。 这是我得到的数组

$aTest = Array
(
    Array
        (
            'date' => 2017-05-04,
            'period' => 'period2',
            'category' => 'Indoor room',
            'score' => 1
        ),

    Array
        (
            'date' => 2017-05-04,
            'period' => 'period5',
            'category' => 'Indoor room',
            'score' => 1
        ),

    Array
        (
            'date' => 2017-05-04,
            'period' => 'period2',
            'category' => 'Indoor room',
            'score' => 2
        ),

    Array
        (
            'date' => 2017-05-04,
            'period' => 'period4',
            'category' => 'Indoor room',
            'score' => 1
        ),

     Array
        (
            'date' => 2017-05-03,
            'period' => 'period5',
            'category' => 'Gym Class',
            'score' => 1
        ),

    Array
        (
            'date' => 2017-05-03,
            'period' => 'period1',
            'category' => 'Gym Class',
            'score' => 1
        ),

     Array
        (
            'date' => 2017-05-03,
            'period' => 'period4',
            'category' => 'Indoor room',
            'score' => 1
        )
        );

这次我喜欢按类别分组并按时期分组总分。 Y 轴是类别，X 轴是周期。 最后我需要这个作为谷歌图表

/*period, total indoor, total gym, 'total indoor', 'total gym'*/
array(
['Period1', 0,1,'0','1'],
['Period2', 3,0,'3','0'],
['Period3', 0, 0,'0','0'],
['Period4', 4,0,'4','0'],
['Period5', 1,1,'1','1']
 )

我有这个 php 代码：

    foreach ($aTest as $value) {
            //echo $value['period'].' - '.$value['score'].'<br/>';

            if (empty($output[$value]['period']))
                $output[$value]['period'] = ['Period1' => 0, 'Period2' => 0, 'Period3' =>0, 'Period4' => 0, 'Period5' => 0];

   if(empty($output[$value]['category']))
        $output[$value['catgeory']] = ['Gym Class' => 0, 'Indoor room' =>0];

            $output[$value['category']] += $value['score'];
        }

        ksort($output);

但这只是按类别而不是按时间段来计算总分。 我想我也需要遍历周期，但是如何？

Answer 1

• 你这里有错误的逻辑。

 if (empty($output[$value]['period'])) $output[$value]['period'] = ['Period1' => 0, 'Period2' => 0, 'Period3' =>0, 'Period4' => 0, 'Period5' => 0];

$value是一个数组，您尝试检查$output[$value]

• 我看到您没有任何行总和周期值。

• 我有你的数据的解决方案。 我的代码是做什么的？？

• 按类别分类的时期总分

• 对于每个合并周期和类别分数到一个数组，使用arraySort category 来设置这些类别分数值的位置

$temp = []; $output = []; foreach($aTest as $value){ $period = $value['period']; $category = $value['category']; // Create default values if (empty($temp[$period])){ $temp[$period] = []; } if(empty($temp[$period][$category])){ $temp[$period][$category] = 0; } //Sum score $temp[$period][$category] += $value['score']; } //After Forech we have an array with ['period name' => ['category name' => score]]; //Sort values of the category change it if you want, you can add more option such as (item type for add '' to values) $arraySort = [ "Indoor room", //total indoor, "Gym Class", // total gym, "Indoor room", //'total indoor', "Gym Class" //'total gym' ]; foreach($temp as $period => $catsScore){ $periodItem = [$period]; foreach($arraySort as $cat){ $periodItem[] = $catsScore; } $output[] = $periodItem; }
