Table data is not arranged - php

Question

as i am a beginner so i want to ask how can i run the multiple queries using PHP for the same row to have multiple data in the table in html. i have tried many attempts but nothing worked i am using MYSQL as backend. I know that i have not written code for the first row and second column i.e. the second <td> on wicket keeper but the thing is that i want all rounder data to come in the second <td> of wicket keeper section. when running this code it is providing the output fine for wicket keeper but for all rounder column the data is starting after the end of wicket keeper data. i know why this problem is occurred but how can i solve this please tell??
CODE HERE:
<?php
$sql="select * from teams where role = 'WicketKeeper'";
$result=mysqli_query($conn,$sql) or die(mysqli_error());
while($row=mysqli_fetch_assoc($result)){
?>
<tr>
<td><?php echo $row["name"] ?></td>
<td></td>
<td></td>
<td></td>
</tr>
<?php } ?>
<?php
$sql="select * from teams where role = 'AllRounder'";
$result=mysqli_query($conn,$sql) or die(mysqli_error());
while($row=mysqli_fetch_assoc($result)){
?>
<tr>
<td></td>
<td><?php echo $row["name"] ?></td>
<td></td>
<td></td>
</tr>
<?php } ?>

Answer 1

Here is a good way to generate the rows of the display you showed.
First, use this query:
SELECT name, role FROM teams ORDER BY role DESC;
It generates rows in the order you want them, wicketkeepers first.
Then, use this php code to generate your display.
<?php
$sql="SELECT name, role FROM teams ORDER BY role DESC";
$result=mysqli_query($conn,$sql) or die(mysqli_error());
while($row=mysqli_fetch_assoc($result)){
$role = $row["role"];
$name = $row["name"];
$wicketkeeper = $role == "WicketKeeper" ? $name : "";
$allrounder = $role == "AllRounder" ? $name : "";
?>
<tr>
<td><?php echo $wicketkeeper ?></td>
<td><?php echo $allrounder ?></td>
<td></td>
<td></td>
</tr>
<?php } ?>
This renders the rows in the result set from your query, placing names in columns according to their roles.
In the general case, this task is known as pivoting a table.
Pro tip 1 Try to avoid SELECT * in queries. Instead give the names of the columns you need. This makes your code easier for a stranger to read, and it may make your queries run faster.
Pro tip 2 Anytime you catch yourself reusing the same query where it only varies by a WHERE clause, try to use a single query. This can make your application run faster.
