如何使用PHP函数返回值的数目

我在代码中使用了一个PHP函数，我希望在调用该函数时返回值。例如，我想返回NR SR HVDC ATT的值，如下所示：

if (isset($_POST['action']) AND ! empty($_POST['action']) AND ( $_POST['action'] == 'allUnitMonthWiseDOne')) {

    $fromdate = date("Y-m-d", strtotime($_POST['fromdate']));
    $todate = date("Y-m-d", strtotime($_POST['todate']));
    $year = date('Y', strtotime($fromdate));
    $y = date("Y-m-d", strtotime($fromdate));
    $fromMon = date('m', strtotime($fromdate));
    $toMon = date('m', strtotime($todate));
    $toChoice = $_POST['toChoice'];
    ?>         

    <table border="1" style="border-collapse: collapse; font-family: verdana,arial,sans-serif;font-size:10px;" width="100%" >
        <tr style="font-weight: 600;">
            <td><?php
    $divQuery = mysqli_query($dbcon, "SELECT * FROM vefm_comp_division WHERE id=" . $_POST['division']);
    $divRow = mysqli_fetch_array($divQuery);
    echo $divRow['division_name'] . ' - ' . date("F Y", strtotime($_POST['fromdate'])) . ' to ' . date("F Y", strtotime($_POST['todate']));
    ?>
            </td>
            <td colspan="13" style="text-align: center;">PL Estimate for the FY <?= $year ?>-<?= $year + 1; ?></td>
        </tr>

        <tr style="font-weight: 600;">
            <?php if ($_POST['division'] == 1) { ?>
                <td><?= $year ?>-<?= $year + 1; ?> PL Estimate</td>
                <td>NR</td>
                <td>SR</td>
                <td>HVDC</td>

            <?php } ?>
        </tr>

        <tr>
            <td>Monthly Budget</td>
            <?php
            $monthlyResult = 0;
            if ($_POST['division'] == 1) {
                $plQuery = mysqli_query($dbcon, "SELECT id FROM vefm_unit_reference where division_id=1");

您最好使用一个数组，比如
$value
，然后对每个项目使用
$value['nr']
，而不是像
$nr
这样单独的值

return $value;

它将以关联数组的形式返回所有值

首先需要创建数组（为每个选项创建一个元素，不要使用我在示例代码中输入的
…
）

然后使用

$value['nr'] += $plResult['monthlyBudgetAmt'];

您的代码中有大量重复，您应该研究如何减少重复，这也将有助于使代码更加清晰。这（IMHO）是目前的一个主要问题。我需要返回值得尊敬的单位（如NR、SR、HVDC、CR、WR等）的值。因此，如果您的任何问题得到解决，您可以将其标记为已回答吗-
$value['nr'] += $plResult['monthlyBudgetAmt'];
