How to set default tags for post in wordpress

Our today's topics are how to set default tags for the post in WordPress. To set default tags for posts we can create a plugin or we can write a function in the WordPress theme function.php file. We can write a function for these topics as following - 

add_action('publish_post','add_default_tags');
function add_default_tags(){
$postId=get_the_ID();
$tags=array('Programming','Tutorial');
wp_set_post_tags($postId,$tags,true);
}

Update function.php or if you write a plugin then active it.

Now write a post and publish it then see it automatically add those tags.
