WordPress query single post by slug

Question

For the moment when I want to show a single post without using a loop I use this:

Answer 1

From the WordPress Codex:

 $the_slug,
  'post_type'   => 'post',
  'post_status' => 'publish',
  'numberposts' => 1
);
$my_posts = get_posts($args);
if( $my_posts ) :
  echo 'ID on the first post found ' . $my_posts[0]->ID;
endif;
?>
