php - 每次我进行查询或从 <th> 标记排序时，对 sql 查询和 ID 重置进行排序并按数字顺序开始

Question

我有一个名为forms1的数据库和一个名为demo的表
表中的字段为ID、Autore、Titolo、cit

我希望第一行能够让我对查询检索到的字母数字值进行排序，例如

如何修改我的代码？ 这是cerca2.php:

<style>
br {margin-bottom:-10px;}
</style>

<form action="cerca2.php" method="post">
<b>Nome</b>&nbsp;<input type="text" name="Nome">&nbsp;&nbsp;
<b>Numero&nbsp;</b><input type="text" name="Numero">&nbsp;&nbsp;
<b>city&nbsp;</b><input type="text" name="city">&nbsp;&nbsp;
<input type="Submit">
</form>

<style>
tr:nth-of-type(odd) { background-color: AZURE; }
tr:nth-of-type(even) { background-color: CYAN; }
</style>
<style>
tr:hover{background-color<img src="images/smilies/biggrin.gif" border="0" alt="">EEPSKYBLUE;}
</style>

<?php

echo "<table border='1' style='border-collapse: collapse;border-color: silver;'>";  
echo "<tr style='font-weight: bold;'>";  
echo "<td width='auto' bgcolor=”#7FFFD4&#8243;>&nbsp;<i>ID<i/></td>";  
echo "<td width='auto' >&nbsp;<i>Nome<i/></td>";
echo "<td width='auto' ></td>";
echo "<td ></td>";
echo "</tr>";

define('DB_NAME', 'forms1');
define('DB_USER', 'root');
define('DB_PASSWORD', '');
define('DB_HOST', 'localhost');

$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if (!$link) {
    die('Could not connect: ' . mysql_error());
}

$db_selected = mysql_select_db(DB_NAME, $link);

if (!$db_selected) {
    die('Can't use ' . DB_NAME . ': ' . mysql_error());
}

$Nome = str_replace(' ', '%', $_POST['Nome']);
$Numero = str_replace(' ', '%', $_POST['Numero']); 
$city = str_replace(' ', '%', $_POST['city']); 

$arNome = str_split($Nome);
$arNumero = str_split($Numero);
$arcity = str_split($city);

$Nome='';
foreach ($arNome as $value) 
{
   if ($value=='%') continue;
   $Nome.=$value.'%';

}

$Numero='';
foreach ($arNumero as $value) 
{
   if ($value=='%') continue;
   $Numero.=$value.'%';

}

$city='';
foreach ($arcity as $value) 
{
   if ($value=='%') continue;
   $city.=$value.'%';

}

$sql = mysql_query("SELECT * FROM demo WHERE Autore LIKE '%$Nome%' AND Titolo LIKE '%$Numero%' AND cit LIKE '%$city%' ORDER BY Autore") or die(mysql_error());

while($row=mysql_fetch_array($sql)){

    echo "<tr>";
    echo "<td width='auto' bgcolor=”#FF0000 &#8243;>" . "&nbsp;". "<b>"  . $row[0] . "&nbsp;". "<b/>". "</td>";
    echo "<td width='auto'>" . "&nbsp;" . $row[1] . "&nbsp;" . "</td>";
    echo "<td width='auto'>". "</td>";
    echo "<td width='auto'>" . "&nbsp;". "<i>" . $row[2] . "<i/>". "&nbsp;" . "</td>";     
    echo "<td width='auto'>" . "&nbsp;". "<i>" . $row[3] . "<i/>". "&nbsp;" . "</td>";
    echo "</tr>";
    
}
mysql_close();
?> 

我会点击Nome和其他th(ID除外)来重新排序值字母数字AZ或ZA，反之亦然。目前，这是我调用查询时的结果页面(查看上面的代码):

我也愿意 - 但我不知道该怎么做 - ID 值总是从 1 开始，并根据每次查询或从 < 排序时检索到的 x 值的数量按数字顺序继续em>th 标签。
在我的例子中，总是依赖于它所代表的值。 从图中您可以看出，数字以随机顺序出现。 在这里，我不想要这个。

尝试这个代码部分:

    $i = 0; while($row=mysql_fetch_array($sql)){
        $i++;
        echo "<tr>";
        echo "<td width='auto' bgcolor=”#FF0000 &#8243;>" . "&nbsp;". "<b>"  . $i . "&nbsp;". "<b/>". "</td>";
        echo "<td width='auto'>" . "&nbsp;" . $row[1] . "&nbsp;" . "</td>";
        echo "<td width='auto'>". "</td>";
        echo "<td width='auto'>" . "&nbsp;". "<i>" . $row[2] . "<i/>". "&nbsp;" . "</td>";     
        echo "<td width='auto'>" . "&nbsp;". "<i>" . $row[3] . "<i/>". "&nbsp;" . "</td>";
        echo "</tr>";

}
