如何在HTML搜索表单中搜索多个ID以获取php的mysql行？ （随机和顺序）

Question

我需要你的帮助..

我可以通过填写选择板作为选项的html表单来查看单个人的结果，并按卷号（123456）搜索以查看所有列...

以下php

<?php

// php code to search data in mysql database and set it in input text

if(isset($_POST['search']))
{
// id to search
$roll = $_POST['roll'];
$board = $_POST['board'];

//connect to the database
include('connect.php');

// mysql search query
$query = "SELECT `firstname`, `lastname`, `roll`, `city`, `board` FROM `result` WHERE `roll` = $roll and `board` = $board  LIMIT 1";
$result = mysqli_query($connect, $query);

// if id exist 
// show data in inputs
if(mysqli_num_rows($result) > 0)
{                            

echo "<table width='540' height='69'><thead><tr>
<th width='14%'><div align='center'>first name</div></th>
<th width='12%'><div align='center'>last name</div></th>
<th width='17%'><div align='center'>roll number</div></th>
<th width='14%'><div align='center'>city</div></th>
<th width='22%'><div align='center'>board</div></th>
</tr></thead>
<tfoot>
</tfoot>
<tbody>
<tr class='alt'>";

    while ($row = mysqli_fetch_array($result))
{
echo "<td><div align='center'>" . $row['firstname'] . "</div></td>";
echo "<td><div align='center'>" . $row['lastname'] . "</div></td>";
echo "<td><div align='center'>" . $row['roll'] . "</div></td>";
echo "<td><div align='center'>" . $row['city'] . "</div></td>";
echo "<td><div align='center'>" . $row['board'] . "</div></td>";
 }
 echo "</tbody>";
 echo "</table>";



   }


   mysqli_free_result($result);
   mysqli_close($connect);

     }

   ?>

现在我想要的是搜索随机卷号..

请查看表单图片

请在我的php中进行更改，以便我可以使用此表单..

随机结果应该是这样的

 firstname   lastname    roll    city     board
 name1       lname1      3456     -         -
 name2       lname2      8765     -         -
 name3       lname3      4567     -         -

也是顺序的，例如在搜索中写入（从1001到1100）以查看100人的结果..

顺序结果应该是这样的

 firstname   lastname    roll    city     board
 name1       lname1      1001     -         -
 name2       lname2      1002     -         -
 name3       lname3      1003     -         -
 .............................................
 name100     lname100    1100     -         -

您需要根据需要更改查询

 $query = "SELECT `firstname`, `lastname`, `roll`, `city`, `board` 
FROM `result` WHERE 1=1 ";

if(isset( $_POST['roll'])){ // Assuming this as single roll text
   $query.=" AND `roll` = '$roll'";
 }
if(isset($_POST['fromroll']) && isset($_POST['toroll'])){ // This as From and To
  $fromroll=$_POST['fromroll'];
  $toroll=$_POST['toroll'];
$query.=" AND roll between '$fromroll' AND '$toroll' ";
 }
if(isset($_POST['multipleroll']))
{
  $multipleroll=$_POST['multipleroll'];
 $query.=" AND roll in ('$multipleroll') "; 
}

$result = mysqli_query($connect, $query);
