從多維數組創建多個HTML表

Question

我正在嘗試從多維數組創建多個HTML表。 我已經建立了一個數組，但是對如何將該數組轉換為多個HTML表一無所知。

我想根據當天打開的時間和班級名稱來分開表格。

為了清楚起見，這是我的代碼：

$title    = [];
$table_rows  = [];

// build table arrays
foreach ($schedule AS $row)
{
    $title[]    = $row->time.' - '.$row->class_name;
    $table_rows[$row->time][$row->class_name][] = ['student_id' => $row->student_id, 'mentor_code' => $row->mentor_code, 'student_name' => $row->student_name];
}

// $title array (using array_unique($title) to removes duplicate values
Array
(
    [0] => 07:30-08:30 - E-1
    [1] => 08:30-09:30 - E-1
    [2] => 10:00-11:00 - E-1
    [3] => 11:00-12:00 - E-1
    [12] => 07:30-08:30 - E-2
    [13] => 08:30-09:30 - E-2
)

// $table_rows array
Array
(
    [07:30-08:30] => Array
        (
            [E-1] => Array
                (
                    [0] => Array
                        (
                            [student_id] => 1012836001
                            [mentor_code] => TPA-1
                            [student_name] => Vanessa
                        )

                    [1] => Array
                        (

                            [mentor_code] => TPA-1
                            [student_name] => Charissa
                        )
                )

            [E-2] => Array

                        )
                    [2] => Array
                        (
                            [student_id] => 3012836003
                            [mentor_code] => TPA-1
                            [student_name] => Charissa

                        (
                            [student_id] => 1012836001
                            [mentor_code] => FIS-1

                    [0] => Array
                        (
                            [student_id] => 1012836001
                            [mentor_code] => FIS-1
                            [student_name] => Vanessa
                        )
                    [1] => Array
                        (
                            [student_id] => 1012836002
                            [mentor_code] => FIS-1

                    [2] => Array
                        (
                            [student_id] => 3012836003
                            [mentor_code] => FIS-1
                            [student_name] => Charissa
                        )
                )
        )
)

從數組中，我將創建如下表：

Time : 07:30-08:30    TPA-1    Class : E-1
|------------|--------------|------------|
|Student ID  | Student Name | Status     |
|------------|--------------|------------|
|1012836001  | Vanessa      | Check None |
|1012836002  | Kesya        | Check None |
|3012836003  | Charissa     | Check None |
|------------|--------------|------------|

Time : 08:30-09:30    TPA-1    Class : E-1
|------------|--------------|------------|
|Student ID  | Student Name | Status     |
|------------|--------------|------------|
|1012836001  | Vanessa      | Check None |
|1012836002  | Kesya        | Check None |
|3012836003  | Charissa     | Check None |
|------------|--------------|------------|

Time : 07:30-08:30     FIS-1   Class : E-2
|------------|--------------|------------|
|Student ID  | Student Name | Status     |
|------------|--------------|------------|
|1012836004  | Drex         | Check None |
|3012836005  | Vulcano      | Check None |
|------------|--------------|------------|

Time : 08:30-09:30     FIS-1   Class : E-2
|------------|--------------|------------|
|Student ID  | Student Name | Status     |
|------------|--------------|------------|
|1012836004  | Drex         | Check None |
|3012836005  | Vulcano      | Check None |
|------------|--------------|------------|

Time : 10:00-11:00    FIS-1    Class : E-1
|------------|--------------|------------|
|Student ID  | Student Name | Status     |
|------------|--------------|------------|
|1012836001  | Vanessa      | Check None |
|1012836002  | Kesya        | Check None |
|3012836003  | Charissa     | Check None |
|------------|--------------|------------|

Time : 11:00-12:00    FIS-1    Class : E-1
|------------|--------------|------------|
|Student ID  | Student Name | Status     |
|------------|--------------|------------|
|1012836001  | Vanessa      | Check None |
|1012836002  | Kesya        | Check None |
|3012836003  | Charissa     | Check None |
|------------|--------------|------------|

我可以根據陣列產生結果嗎？ 我真的需要幫助 如果有人可以將我指出正確的方向，將不勝感激。 謝謝。

您可以通過減少數組的多維性來簡化此過程。

將計划行按完整標題分組：

foreach ($schedule as $row)
{
    $title = "Time : $row->time   $row->mentor_code   Class : $row->class_name";
    $tables[$title][] = $row;
}

然后，您將獲得一個按標題索引的表數組。 從這一點來看，輸出每個表要簡單得多。

foreach ($tables as $title => $table) {
    echo $title;
    echo '<table>
            <thead>
              <tr>
                <th>Student ID</th>
                <th>Student Name</th>
                <th>Status</th>
              </tr>
            </thead>
            <tbody>';
    foreach ($table as $row) {
        echo "<tr>
                <td>{$row->student_id}</td>
                <td>{$row->student_name}</td>
                <td>Check None</td>
              </tr>"
    }
    echo '</tbody>
          </table>';
}
