PHP规范化，如何创建适当的循环？

我尝试将我的表预订分为3个表以实现规范化。 嗯，当我尝试为多个预订生成1个bookingID时，我遇到了问题。 我对循环感到困惑

场景：客户预订了两个展位，A01和A02（A01从第1天预订到第3天，而A02从第1天预订到第2天）。

系统将处理预订，它应该为A01和A02生成2个预订ID，并为A01_D1、A01_D2、A01_D3（携带预订ID A01）和A02_D1、A02_D2（携带预订ID A02）生成预订日程ID。我应该如何循环并获得以下结果

我的编码

<?php

include('db.php');

// check array and insert parrentBookingID

// check submitted totalDay
if (isset($_POST['submit']) && isset($_POST['totalDay'])) {

    //check day exist or not
    $cDay=$_POST['totalDay'];

    for ($i=1; $i<=sizeof($cDay); $i++) { //check array size    
        $temp=0;

        foreach ($cDay as $dy) {
            $checkDay = $dy;
            $checkDay = explode(" ", $checkDay);

请将代码包装在大约80个字符之后。在许多语言中，这是一个推荐的标准，必须水平滚动是相当不愉快的。@mike，我知道的没错！我试着尽可能地重新格式化它。。但是那家伙用标签代替空格，所以花了很长时间！现在我已经厌倦了格式化，甚至都不想去读了。我用的是回车和空格，哈哈。我怎么知道我应该用制表符或空格@。@对不起
