Question

我有一个名为约会的表格，字段是医生，日期，时间，appuser（即患者）。我想打印链接中显示的第一个表。我已经显示了第二个，但现在我想把它改成第一个。

I want to display first one, see Image

这是我目前第二个表的代码：

<div id="grid"> 
    <ul>
        <li>Time</li>
        <li>Doctor Name</li>            
        <li>Patient Name</li>
    </ul>
</div>
<?php   

    if($_POST['submit'] == "Search")
    {
        $select= $_POST['datesel'];
        $s = mysql_query("select * from appntt where date = '".$select."'");
    }
    else
    {
        $d= date("j/n/Y");
        $s=mysql_query("select * from appointment where date = '".$d."' ORDER BY time ASC");
    }
    $a=1;

    while($fetch=mysql_fetch_array($s))
    {
        if($fetch['time'] > '12:00')
        {
            $y = $fetch['time'].' PM';
        }
        else
        {
            $y= $fetch['time'].' AM';
        }

?>          
<div id="grid1">
    <ul>             
        <li><?php echo $y; ?></li>
        <li><?php echo $fetch['doctor']; ?></li>
        <li><?php echo $fetch['appuser']; ?></li>
    </ul>
</div>
<?php $a++; } ?>

首先应该在php中的数组中对结果进行排序，然后根据此数组打印表。

首先，我们需要一个数组来对查询结果进行排序。这个数组到底会是二维的。我们还需要记住所有医生，因为从排序的约会中提取它们会更有效：

$table = []; //The array for the sorted appointments
$doctors = []; //The array for the doctors

然后我们需要处理查询结果并将它们排序到数组中：

while($fetch=mysql_fetch_array($s)){
    // The keys of the first dimension will be the appointment time 
    // and the key of the second dimension will be the doctor
    // So we can access a specific appointment by $table[time][doctor]
    $table[$fetch['time']][$fetch['doctor'] = $fetch['appuser'];

    //save the doctors name
    $doctors[] = $fetch['doctor'];
}
array_unique($doctors); // delete duplicate values, so that we have just
                        // the names of all the doctors

现在我们需要打印表格：

> <table> 
    <tr>
        <td> TIME </td> <? 
        foreach($doctors as $doctor){
            > <td> <? echo $doctor > </td> <? //print the header
        }
    > </tr> <?
// Depending on the result of your query, 
// you might need to order the array first or the times will be mixed up.
foreach($array as $time=>$appointments){ //loop over all the times. 
    > <tr> 
        <td> <? echo $time; > </td> <? //first column: print appointment time
        foreach($doctors as $doctor){
            > <td> <?
                if($appointments[$doctor] != null){
                    echo $appointments[$doctor]; //other columns: print patient name
                }
                // if there is no appointment, you might need to add a 
                // non-breakable-space to the cell
            > </td> <?
        }
    > </tr> <?
}
> </table>

这有望成功。我不能保证它开箱即用，因为我无法测试它，但我认为你可以得到这个想法。

旁注：从不将用户的值直接插入数据库查询！这使您容易受到SQL注入的攻击。</ p>
