if I just want results based on var value set or not? so that I can simply use this

$lab_type=$label['type']??null;

but if want to compare $label['type'] response with using ?? operator, then how to do.

want to change it

 <option value="background" <?= isset($label['type'])?$label['type']=='background'?'selected':'':'selected'?> >Background</option>

don't want to use isset here.

Change your ternary operator to:

<?= ($label['type'] ?? null) == 'background' ? 'selected' : '' ?>
