Wordpress中的意外数字wp_get_attachment_thumb_url

Question

I am trying to print url of the thumbnail out side the wordpress directory, the url works but the problem is I am always getting a number before that url.

This is the code I am playing with,

<?php require($_SERVER['DOCUMENT_ROOT'] . '/personal/wordpress/wp-load.php'); query_posts('showposts=1');  if (have_posts()) : while (have_posts()) : the_post(); ?>

<?php echo wp_get_attachment_thumb_url( get_post_thumbnail_id( the_id() ) )?>

<?php endwhile; else: echo "no posts"; endif; ?>

This is the output:

5http://localhost/personal/wordpress/wp-content/uploads/2013/10/facebookhero-150x150.jpg

I have already tried string replace, like this str_replace(the_id(),"", wp_get_attachment_thumb_url( get_post_thumbnail_id( the_id() )) but it does not work, in fact when I have tried:

 <?php echo "|".wp_get_attachment_thumb_url( get_post_thumbnail_id( the_id() ) )?>

Most interestingly this is what I get:

5|http://localhost/personal/wordpress/wp-content/uploads/2013/10/facebookhero-150x150.jpg

It works fine:

simplexml_load_string(get_the_post_thumbnail())->attributes()->src
