get_the_tags( int|WP_Post $post_id )

More Information

This function returns an array of objects, one object for each tag assigned to the post. If this function is used in The Loop, then no ID need be passed.

This function does not display anything; you should access the objects and then echo or otherwise use the desired member variables.

The following example displays the tag name of each tag assigned to the post (this is like using the_tags(), but without linking each tag to the tag view, and using spaces instead of commas):

<?php
$posttags = get_the_tags();
if ($posttags) {
  foreach($posttags as $tag) {
    echo $tag->name . ' '; 
  }
}
?>
