在 php 中为房间预订系统创建 HTML 表

Question

我必须为房间预订系统创建一个 html 表，但我在想办法将数据插入单元格时遇到了困难。目前我正在从数据库中获取数据（预订的开始时间和结束时间）。然后我循环遍历数组中的时间，并使用 if 语句将开始时间与时间数组中的时间进行比较。

这是我目前拥有的： 客房预订图片

我遇到的主要问题是，在我的数据库中，如果同一天有两个预订，它只会显示数组中的最后一个。

    $tableStart = "<table class='table_main'><thead><tr id='table_first' class='first_last'><th class='first_last'>Time:</th>";
    $tableMid = "</tr></thead><tbody>";
    $tableEnd = "</tbody></table>";

    foreach ($newBookings as $booking) {
        $tableStart .= "<th class='first_last'>$booking[0]</th>";
    }

    foreach ($times as $time) {
        $tableMid .= "<tr class='even_row'><td class='time'>{$time['times']}</td>";
        $i = 0;
        foreach ($newBookings as $booking) {
            unset($booking[0]);
            $x = count($booking);
            if ($x > 0) {
                if ($booking[$i]['start_Time'] == $time['times']) {
                    $tableMid .= "<td class='new'>{$booking[$i]['start_Time']}</td>";
                } else if($booking[$i]['end_Time'] == $time['times']) {
                    $tableMid .= "<td class='new'>{$booking[$i]['end_Time']}</td>";
                } else {
                    $tableMid .= "<td class='new'></td>";
                }
            } else {
                $tableMid .= "<td class='new'></td>";

            }

            ++$i;
        }
    }

    $tableStart .= $tableMid;
    $tableStart .= $tableEnd;
    return $tableStart;`

我目前在数组中设置数据的方式如下所示：

$times = [
0 => ['06:00'],
1 => ['06:30'],
2 => ['07:00'],
3 => ['07:30'],
4 => ['08:00'],
5 => ['08:30'],
6 => ['09:00'],
7 => ['09:30'],
8 => ['10:00'],
9 => ['10:30'],
10 => ['11:00'],
11=> ['11:30'],
12 => ['12:00'],
13 => ['12:30'],
14 => ['13:00'],
15 => ['13:30'],
16 => ['14:00'],
17 => ['14:30'],
18 => ['15:00'],
19 => ['15:30'],
20 => ['16:00'],
21 => ['16:30'],
22 => ['17:00'],
23 => ['17:30'],
24 => ['18:00'],];

        $newBookings = [
        0 => [
            0 => 'Room 33'
        ],
        1 => [
            0 => 'New room 8',
            1 => [
                'room_Name' => 'New room 8',
                'start_Time' => '11:30',
                'end_Time' => '12:30'
            ]
        ],
        2 => [
            0 => 'sds',
            1 => [
                'room_Name' => 'sds',
                'start_Time' => '09:30',
                'end_Time' => '11:30'
            ],
            2 => [
                'room_Name' => 'sds',
                'start_Time' => '14:30',
                'end_Time' => '16:30'
            ]
        ],
        3 => [
            0 => 'New Room 3'
        ],
        4 => [
            0 => 'NewRoom5'
        ],
        5 => [
            0 => 'New room 55'
        ]
    ];

对于看到此问题的任何人，我找到了解决方法，我使用了 ADyson 对阵列的建议并重新编写了我的代码，以便它现在可以正常工作。对于任何对此感兴趣的人是我使用的代码：

public function render(): string
{

    $data = $this->tableData; //from abstract class contains table data
    $times = $this->tableTimes; //gets times
    $rooms = $this->roomNames; //gets room names
    $startTime = $times[0]['start_time']; //sets the start time
    $endTime = $times[0]['end_time']; // sets the end time
    $times = $this->setTimeArray($startTime, $endTime); //goes to function
    $newBookings = $this->setDataArray($data, $rooms); // goes to function


    $tableStart = "<table class='table_main'><thead><tr id='table_first' class='first_last'><th class='first_last'>Room:</th>";
    $tableMid = "</tr></thead><tbody>";
    $tableEnd = "</tbody></table>";

    foreach ($times as $key => $time) {
        $tableStart .= "<th class='first_last'>{$time}</th>";
    }

    foreach ($newBookings as $booking) {
        $tableMid .= "<tr class='even_row'><td class='room_Name'>{$booking['Room']}</td>";
        $x = 0;
        $e = 0;

        foreach ($times as $time) {

            if ($x == count($booking['Bookings'])) {
                $x = 0;
            }
            if ($e == count($booking['Bookings'])) {
                $e = 0;
            }

            if (count($booking['Bookings']) < 1) {
                $tableMid .= "<td class='new'></td>";
            } else if ($booking['Bookings'][$x]['start_Time'] == $time) {
                $tableMid .= "<td class='room_Booked'>{$booking['Bookings'][$x]['start_Time']}</td>";
                $x++;
            } else if ($booking['Bookings'][$e]['end_Time'] == $time) {
                $tableMid .= "<td class='room_Booked'>{$booking['Bookings'][$e]['end_Time']}</td>";
                $e++;
            } else {
                $tableMid .= "<td class='new'></td>";
            }

        }

    }

    $tableStart .= $tableMid;
    $tableStart .= $tableEnd;
    return $tableStart;
}

将时间设置为数组

    public function setTimeArray($startTime, $endTime)
{
    $i = 0;
    $endTimes = strtotime($endTime);
    $endTime = date("H:i", strtotime('+30 minutes', $endTimes));
    do {
        $times[$i] = $startTime;
        $time = strtotime($startTime);
        $startTime = date("H:i", strtotime('+30 minutes', $time));
        $i++;
    } while ($startTime != $endTime);

    return ($times);
}

将房间预订数据放入一个数组中

public function setDataArray($data, $rooms)
{
    $newBookings = [];

    $x = 0;
    foreach ($rooms as $key) {
        $newBookings[$x] = array(
            'Room' => $key['room_name'], 'Bookings' => []
        );
        $y = 0;
        foreach ($data as $value) {
            if ($value['room_name'] == $newBookings[$x]['Room']) {
                $newBookings[$x]['Bookings'][$y] = [
                    'room_Name' => $value['room_name'],
                    'start_Time' => $value['requested_time'],
                    'end_Time' => $value['requested_time_end']
                ];
                $y++;
            }
        }
        $x++;
    }
    return ($newBookings);

}
