Title in View or in Controller [SOLVED]

@InsiteFX is right. It depends but I would go with the first option but not typing this way

PHP Code:

<?php if(isset($meta_title) && !empty($meta_title)): ?>
    <?= '<title>'.esc($meta_title).'</title>'; ?>
<?php endif; ?>

but shortly this way

PHP Code:

<title><?php echo $title ?? 'No title' ; ?></title>
