   Displaying small excerpts from latest posts

   If you want to display the latest posts on your WordPress blog, but only the content which comes before the <!--more--> tag, you can use this:

   
   <ul>
   $post = get_post();
   
   $myposts = get_posts( array(
   	'posts_per_page' => 5
   ) );
   
   foreach( $myposts as $post ) : setup_postdata( $post );  
       $content_arr = get_extended ( $post->post_content );
   	?>
       <li>
          <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
          </br>
          <?php echo $content_arr['main']; // Display the part before the more tag  ?>   
       </li>
   <?php endforeach; ?>
   </ul>
   

   Note: $content_arr['extended'] contains the contents after the more tag.
