php - 将设定日期的mysql记录合并到时间表中？

Question

我正在尝试为 5 人的日常使用制定一个小型约会时间表。我现在遇到的唯一问题是将时间表显示同一员工的所有约会到一栏中。我尝试了几种不同的方式，但到目前为止没有运气。我将发布我得到的最好的两次尝试。

下面是我从第一次尝试编写的代码中得到的示例输出。

它单独显示约会，因为对该输出的查询只是对该员工在指定日期的正常查询。我的问题是我找不到将这 3 条记录组合起来并将其输出到此时间表中的一列的方法。至于现在，如果我每个人都有 5 个约会，那么这将显示 25 条记录（25 列），这将无法正常工作。根据我到目前为止的代码，我可以想到一种快速的解决方法，但我不想使用它。这将一次只显示一名员工。但是这种方式对于要标记约会的女孩来说是困难的，因为她可能会忽略时间表并给客户错误的日期/时间。

第二次尝试。我只用日期、时间、人员和事件重写了 mysql。我使用 concat 将时间和事件放入一个字符串中。所以我使用的查询只是调用这个，日期和员工姓名。然后我将这些结果放入一个数组中并提取它们。

这是结果。

0945 Event A part 1
1115 Event A part 2
1315 Event B part 1
1630 Event B part 2
1745 Event B part 3
1900 Event C part 1
1945 Event C part 2
2015 Event B part 4

但后来我不知道我该怎么做才能把它们很好地纳入时间表。我可以把它们放在一张桌子上，但它不会显示那些让阅读变得困难的空槽。

下面是我用于此尝试的代码。

<?php
include("connect.php");//connect to the database.
$todaydate = "11/22/2013";
$staffd = "Jerry";

$query = 'SELECT CONCAT(time," ",event) FROM appointment3 where date="'.$todaydate.'" AND staff="'.$staffd.'"';
$result = mysql_query($query) or die ("no query");

$result_array = array();
while($row = mysql_fetch_assoc($result))
{
    $new_arr[] = $row['CONCAT(time," ",event)'];    
}
sort($new_arr);
foreach ($new_arr as $value) {
    echo $value."<br />\n";
}
?>

欢迎任何建议，因为我仍然认为我的方式不会很好......

首先：不是让 500 行回显<tr>...</tr>，而是循环遍历它们。

如果空窗口困扰您，只需生成它们！它不像它们包含任何东西，所以你可以这样做来填补缺失的时间。

如果您的时间表存储在关联数组中，可以使用类似

$lines = ...;

$hours = [];
foreach ($lines as $line)
{
    $hour = substr($line, 0, 4);
    $hours[$hour] = $line;
}

然后，您可以使用以下方法生成默认的空事件：

for ($i = 0; $i < 24; $i ++)
    for ($j = 0; $j < 60; $j += 5)
    {
        $hour = sprintf('%02d%02d', $i, $j);
        if (!isset($hours[$hour]))
            $hours[$hour] = "$hour (empty)";
    }

var_dump($hours);
