Remove extra generated td values from the table

I’m trying to fill table with values which I’m getting from the database but when I loop though array some values are getting out of the table.

Code:

$query = "SELECT * FROM monthly_report";
$result = $this->db->query($query)->result_array();

$data['data'] = $result;

<table class="table table-hover table-striped">
    <thead>
        <tr>
            <th style="text-align:center;">Month</th>
            <th style="text-align:center;">Total Register</th>
            <th style="text-align:center;">January</th>
            <th style="text-align:center;">February</th>
            <th style="text-align:center;">March</th>
            <th style="text-align:center;">April</th>
            <th style="text-align:center;">May</th>
            <th style="text-align:center;">June</th>
            <th style="text-align:center;">July</th>
            <th style="text-align:center;">August</th>
            <th style="text-align:center;">September</th>
            <th style="text-align:center;">October</th>
            <th style="text-align:center;">November</th>
            <th style="text-align:center;">December</th>
        </tr>
    </thead>

    <tbody>
        <?php
        $num = 0;
        for ($m = 1; $m <= 12; $m++) {
            $month = date('F', mktime(0, 0, 0, $m, 1, date('Y')));
            echo "<tr style='text-align:center;'>";
            echo "<td>" . $month . "</td>";


            $short_month_name = date('M', strtotime("2022-$m-01"));

            if (isset($data[$num]['month']) && $data[$num]['month'] == $short_month_name) {

                $decode_data = json_decode($data[$num]['data'], true);
                $decode_isset = isset($decode_data[$short_month_name]) ? $decode_data[$short_month_name] : '';

                echo "<td>" .  $decode_isset . "</td>";
            }

            $num_1 = 0;
            for ($day = 1; $day <= 12; $day++) {

                $short_month_name_1 = date('M', strtotime("2022-$day-01"));

                if (isset($data[$num]['month']) && $data[$num]['month'] == $short_month_name_1) {

                    $decode_data_1 = json_decode($data[$num]['data'], true);
                    $decode_isset_1 = isset($decode_data_1) ? $decode_data_1 : [];

                    foreach ($decode_isset_1 as $v) {

                        if (!empty($v)) {
                            echo "<td>" .  $v . "</td>";
                        } else {
                            echo "<td>0</td>";
                        }
                    }
                } else {
                    echo "<td>0</td>";
                }

                $num_1++;
            }

            echo "</tr>";
            $num++;
        }
        ?>
    </tbody>
</table>

And output is:
