how to echo a custom taxonomy term from an array of term

Question

I have custom post type products & custom taxonomy product_type which has many terms & the products can have multiple product_type terms assigned to it Ex. A Samsung TV Model post has product_type as New arrivals , featured & tv . I am trying to output only the specific custom taxonomy term [hyperlink] from an array on a single products post :-

if( has_term( array( 'laptop', 'TV', 'phone', 'tablet' ), 'product_type' ) ) :
  // Do stuff here
else :
  // DONT SHOW ANYTHING
endif;
?>

entering a text instead of // Do stuff here in above code works. I want to echo the actual tax term from that array. Tried echo $term; , echo get_the_term(); but it doesnt work. How do i output the custom term from this array ?

You're checking if a product_type has a term using has_term(). Now you need to actually get the terms using get_terms(). That function can technically return from 1 to 4 terms. If more than one of the terms is set, you'll need to pick one. In the following code, I chose the first since there's guaranteed to be at least one term.

if( has_term( [ 'laptop', 'TV', 'phone', 'tablet' ], 'product_type' ) ) {
  //* Get the terms
  $terms = get_terms( [
    'taxonomy' => 'product_type',
    'slug'     => [ 'laptop', 'TV', 'phone', 'tablet' ],
  ] );
  //* There could still be up to 4 terms, so use the first
  echo $terms[0]->name;
}
