How to display values already selected in a select (PHP) - php

Question

In need some help on this.
I have a form with a select who works perfectly and add all the values selected in my database. But now I want to do my update form, and I want that when I click to modify a user and arrive on the form, the values are already selected.
For example if in my first form, if I had selected the values 1 and 2, I would like 1 and 2 to be already selected when i go to the modification form. I've already did that :
<?php
$nomLogiciel = getDemandeNomLogiciel($id_demande)[0];
$nom = explode(", ", $nomLogiciel);
foreach ($nom as $item) {
$profilsTmp = getProfilByLogiciel($item); ?>
<div class="form-floating mb-3">
<select class="form-control selectpicker" id="id_profil" name="id_profil[]" multiple data-live-search="true">
<?php foreach ($profilsTmp as $item2) { ?>
<option value="<?php echo $item2['id_profil']; ?>"><?php echo $item2['profil']; ?></option>
<?php } ?>
</select>
<label for="id_profil">Profil <?php echo $item ?></label>
</div>
<?php } ?>
I already managed to do it with a simple select like this :
<select class="form-control selectpicker" id="nomPole" name="nomPole">
<option value="Ambulatoire" <?php if ($one['pole'] == "Ambulatoire") { echo ' selected="selected"'; } ?>>Ambulatoire</option>
<option value="Habitat et Vie Sociale" <?php if ($one['pole'] == "Habitat et Vie Sociale") { echo ' selected="selected"'; } ?>>Habitat et Vie Sociale</option>
</select>
But I would like to know how to do it with multiple values in a foreach ?
If you need my SQL function :
function getDemandeNomLogiciel($id_demande) {
global $bd;
$stmt = $bd->prepare('SELECT nom_logiciel FROM demandes WHERE id_demande = :id_demande');
$stmt->bindParam(ID_DEMANDE, $id_demande);
$stmt->execute();
return $stmt->fetch();
}
function getProfilByLogiciel($nomLogiciel) {
global $bd;
$stmt = $bd->prepare('SELECT * FROM profils_logiciels WHERE nom_logiciel = :nomLogiciel');
$stmt->bindParam(NOM_LOGICIEL, $nomLogiciel);
$stmt->execute();
return $stmt->fetchAll();
}
Thanks for your help !

I tried this and it worked very well. I just check if the values of my previous request can be found in the database. If yes I select them :
<?php
foreach ($structures as $item) { ?>
<option value="<?php echo $item['id_structure']; ?>"
<?php if ($item['id_structure'] == $structurePrincipaleID['id_structure']) { echo ' selected="selected"'; } ?>>
<?php echo $item['nom_structure'] ?></option>
<?php } ?>
