Yii framework combined with charjs to achieve statistical 30 day data method

In this paper, an example of Yii framework combined with charjs to achieve statistical 30 days of data. The details are as follows:

In theory, there should be 30 days of data, but in fact it is not necessarily, so it needs to be completed

public static function getDayOrderCharData($days = 30) {
    $nowday = date ('y-m-d ', strtotime (' - 1day '); // current previous day
    $lastday = date ("y-m-d", strtotime ('-' $days.'day '); // days before
    $daysFormat = [];
    //Gets the date of the days section
    for($i = $days; $i > 0; $i--) {
      $daysFormat[] = date("Y-m-d", strtotime('-'.$i.'day'));
    }
 
    //All users
    $allOrderData = self::find()
            ->select(['FROM_UNIXTIME(create_at,"%Y-%m-%d") as char_time', 'COUNT(id) as total_order', 'SUM(order_amount) as total_order_amount', 'SUM(pay_amount) as total_order_pay_amount'])
            ->where(['>=', 'FROM_UNIXTIME(create_at,"%Y-%m-%d")', $lastDay])
            ->andWhere(['<=', 'FROM_UNIXTIME(create_at,"%Y-%m-%d")', $nowDay])
            ->groupBy('char_time')
            ->all();
    $dayCountTitle   = Yii::t('backend', 'day_order_count_title', ['last_day' => $lastDay, 'now_day' => $nowDay]);
    $dayAmountTitle  = Yii::t('backend', 'day_order_amount_title', ['last_day' => $lastDay, 'now_day' => $nowDay]);
 
    $labels = $daysFormat;
    //All users
    $ordercounts = []; // order quantity
    $orderamounts = []; // order amount
    $orderpayamounts = []; // payment amount
    $allOrderDataArr = [];
    foreach($allOrderData as $allKey => $allVal) {
      $allOrderDataArr[$allVal->char_time]['char_time'] = $allVal->char_time;
      $allOrderDataArr[$allVal->char_time]['total_order'] = $allVal->total_order;
      $allOrderDataArr[$allVal->char_time]['total_order_amount'] = $allVal->total_order_amount;
      $allOrderDataArr[$allVal->char_time]['total_order_pay_amount'] = $allVal->total_order_pay_amount;
    }
 
    foreach($daysFormat as $key => $val) {
      if(array_key_exists($val, $allOrderDataArr)) {
        $orderCounts[] = $allOrderDataArr[$val]['total_order'];
        $orderAmounts[] = $allOrderDataArr[$val]['total_order_amount'];
        $orderPayAmounts[] = $allOrderDataArr[$val]['total_order_pay_amount'];
      } else {
        $orderCounts[] = '0';
        $orderAmounts[] = '0';
        $orderPayAmounts[] = '0';
      }
    }
    $data = [
      'dayCountTitle'    => $dayCountTitle, 
      'dayAmountTitle'    => $dayAmountTitle,
      'orderCountLabel'   => Yii::t('backend', 'day_order_count_label', ['days' => $days]),
      'orderAmountLabel'   => Yii::t('backend', 'day_order_amount_label', ['days' => $days]),
      'orderPayAmountLabel' => Yii::t('backend', 'day_order_pay_amount_label', ['days' => $days]),
      'nowDay'        => $nowDay,
      'lastDay'       => $lastDay,
      'labels'        => $labels,
      'orderCounts'     => $orderCounts,
      'orderAmounts'     => $orderAmounts,
      'orderPayAmounts'   => $orderPayAmounts
    ];
    return $data;
  }

//Get order quantity by day
  var dayOrderCountChartCanvas = $('#dayOrderCountChart').get(0).getContext('2d')
  var dayOrderCountChartData = {
   labels : <?= json_encode($dayOrderChar['labels'], true) ?>,
   datasets: [
    {
     label        : '<?= $dayOrderChar['orderCountLabel'] ?>',
     backgroundColor   : 'rgba(0, 192, 293, 0.5)',
     data        : <?= json_encode($dayOrderChar['orderCounts'], true) ?>
    }
   ]
  }
 
  var dayOrderCountChartOptions = {
    scales: {
      xAxes: [{
        gridLines: {
          display: false
        }
      }],
      yAxes: [{
        gridLines: {
          display: false
        }
      }]
    }
  }
 
  var dayOrderCountChart = new Chart(dayOrderCountChartCanvas, {
    type: 'line',
    data: dayOrderCountChartData,
    options: dayOrderCountChartOptions
  });
 
  //Get order and amount by day
  var dayOrderAmounCanvas = $('#dayOrderAmountChart').get(0).getContext('2d')
  var dayOrderAmounData = {
   labels : <?= json_encode($dayOrderChar['labels'], true) ?>,
   datasets: [
    {
     label        : '<?= $dayOrderChar['orderAmountLabel'] ?>',
     backgroundColor   : 'rgba(0, 192, 293, 0.5)',
     data        : <?= json_encode($dayOrderChar['orderAmounts'], true) ?>
    },
    {
     label        : '<?= $dayOrderChar['orderPayAmountLabel'] ?>',
     backgroundColor   : 'rgba(0, 166, 90, 0.5)',
     data        : <?= json_encode($dayOrderChar['orderPayAmounts'], true) ?>
    }
   ]
  }
 
  var dayOrderAmounOptions = {
    scales: {
      xAxes: [{
        gridLines: {
          display: false
        }
      }],
      yAxes: [{
        gridLines: {
          display: false
        }
      }]
    }
  }
 
  var dayOrderAmountChart = new Chart(dayOrderAmounCanvas, {
    type: 'line',
    data: dayOrderAmounData,
    options: dayOrderAmounOptions
  });

Remember, Yii’s as must define common variables in the model

public $char_ Time; // statistics by time
  public $total_ Order; // all orders
  public $total_ order_ Amount; // total amount of all orders
  public $total_ pay_ Order; // pay the order
  public $total_ pay_ Amount; // total order amount
  public $total_ order_ pay_ Amount; // total payment
