I am able to do the listing correctly, but some values are duplicated and I wanted to remove them and I can not at all ... if anyone can help me, I am very grateful.
// Creating Variable
$sector_list = $s->getSector();
// Listing
<?php foreach($sector_list as $value): ?>
<option>
<?php echo $value['sector']; ?>
</option>
<?php endforeach; ?>
The return happens correctly, but with duplicate values.
