PHP'不等于'多个类别

Question

I'm trying to target all categories in WooCommerce that aren't 'Coffee','Subscription for Me' or 'Gift Vocuhers'. So, any category apart from these three should display the <h3> tag.

The code below works when I target any category apart from 'Coffee':

<? if ($categoryName != "coffee") : ?>
    <h3><? echo $product["title"]; ?></h3> 
<? endif; ?>

However, when I try to target eliminate multiple categories, it doesn't work. How can I adjust the first piece of code to allow multiple categories to be ignored?

My attempt (not working):

<? if ($categoryName != "coffee" || "subscription-for-me" || "gift-vouchers") : ?>
    <h3><? echo $product["title"]; ?></h3> 
<? endif; ?>

Thanks

A more extendable version and possibly cleaner could be to use in_array() like so:

<? if (!in_array($categoryName, ["coffee", "subscription-for-me", "gift-vouchers"])): ?>
    <h3><?php echo $product["title"]; ?></h3> 
<? endif; ?>
