   This example prints the tags of current post:
   Code must be used in The Loop.

   
   $post_tags = get_the_tags();
   
   if ( $post_tags ) {
   	foreach( $post_tags as $tag ) {
       echo $tag->name . ', '; 
   	}
   }
   

Example using post ID to get tags:
This doesn’t need to be in The Loop.

$post_tags = get_the_tags( 24 );

print_r( $post_tags );

/*
This above prints the tag objects for post ID

Print only the first tag name:

$post_tags = get_the_tags();
if ( $post_tags ) {
    echo $post_tags[0]->name; 
}

Execute code based on different tag values:
This code displays different HTML for different tags. Add elseif statements as needed.

<?php
$post_tags = get_the_tags();
foreach( $post_tags as $tag) :
	if ( $tag->name === 'tag-1' ) :
?>

<p>Display HTML for posts tagged with 'tag-1'.</p>

<?php
	elseif ( $tag->name === 'tag-2' ) :
?>

<p>Display HTML for posts tagged with 'tag-2'.</p>

<?php
	else :
	// Post has neither tag, do nothing.
	endif; 
endforeach;
?>

Function to show tags in a dropdown:

<?php
function dropdown_tags(){
	echo '<select name="tag" id="tag" class="postform">';
    foreach ( get_the_tags() as $tag ) {
        echo '<option value="' . $tag->name . '">' . $tag->name . "</option>\n";
    }
    echo '</select>';
}
?>
<h2><?php _e( 'Tags:', 'textdomain' ); ?></h2>
<form id="tags-select" class="tags-select" action="<?php echo esc_url( home_url( '/' ) ); ?>" method="get">
    <?php dropdown_tags(); ?>
    <input type="submit" name="submit" value="view" />
</form>

Loop with tag post by ID and Link to -> /tag/slug:

                              // GET TAGS BY POST_ID
                               $tags = get_the_tags($post->ID);  ?>
 
                               <ul class="cloudTags">

                                    <?php foreach($tags as $tag) :  ?>

                                   <li>
		  <a class="btn btn-warning"
                                          href="<?php bloginfo('url');?>/tag/<?php print_r($tag->slug);?>">
                                                <?php print_r($tag->name); ?>
                                       </a>	
                                    </li>
                                    <?php endforeach; ?>
      </ul>
