Mysql returns duplicate in html table - php

Question

I am trying to populate html table with data from mysql.But i am stuck on this part where each time i add some data it keeps repeating. On the picture below you can see that Test 1 repeat each time for every P20,P21,P24,P22,P23 and i needed to be one TEST1 for all of them. When i add Test 2 with value 19000 its making new P20 and all data come from Test 1 to Test 2. Can someone help me how to fix this.Any hint or suggestion wil be appreciated. Thank you all very much (Sorry for my bad english)
This is code that runs this
$sql = 'SELECT DISTINCT Pers.naam, Rol.funkcija,pdata.broj
FROM ids
left JOIN Pers ON ids.persid = Pers.id
left JOIN Rol ON ids.rolid = Rol.id
left JOIN pdata ON ids.pdataid = pdata.id
';
$query = $conn->prepare($sql);
$query->execute();
$testing = $query->fetchAll(PDO::FETCH_ASSOC);
?>
<table>
<tr>
<th>P Small <small>(NONE)</small></th>
<?php
foreach ($testing as $test):
?>
<th>
<?php
echo $test['naam'] . '<br />';
?>
</th>
<?php
endforeach;
?>
</tr>
<tr>
<th>TESTING LINES</th>
</tr>
<?php foreach ($testing as $test): ?>
<tr>
<td><?php echo $test['funkcija']; ?></td>
<?php endforeach; ?>
<?php
foreach ($testing as $test):
?>
<td><?php echo $test['broj']; ?></td>
<?php
endforeach;
?>
</tr>
</table>
I would like to have it like this

Answer 1

There is some refactoring required to get to the output you want.
You seem to be enumerating quite a lot of data from your SQL result, so there is some grouping required to make things easier.
To get the appropriate number to each "naam" and "funkcija" you can use array_filter which however could theoretically return several numbers in each case.
You'll also have to nest a couple foreach instead of running them after one another.
If I understand your data structure correctly, this should at least give you a good starting point for the output you want:
<?php
// ...
$testing = $query->fetchAll(PDO::FETCH_ASSOC);
$naams = array_unique(array_column($testing, "naam"));
$funkcijas = array_unique(array_column($testing, "funkcija"));
?>
<table>
<tr>
<th>P Small <small>(NONE)</small></th>
<?php foreach ($naams as $naam): ?>
<th>
<?php echo $naam; ?>
</th>
<?php endforeach; ?>
</tr>
<tr>
<th>TESTING LINES</th>
</tr>
<?php foreach ($funkcijas as $funkcija): ?>
<tr>
<td><?php echo $funkcija; ?></td>
<?php foreach ($naams as $naam): ?>
<?php
$data = array_filter(
$testing,
function ($v) use ($naam, $funkcija)
{
return $v["naam"] === $naam && $v["funkcija"] === $funkcija;
}
);
foreach ($data as $value): ?>
<td><?php echo $value["broj"]; ?></td>
<?php endforeach; ?>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
</table>
