just a simple PHP question

How would be the better way of writing this code:

the aim: the custom post type name should link to blog/custom_post_type

this snippet here works – but how could I do it better?

<?php
	echo ('<a href="');

	$url = get_home_url(); echo $url;

	echo ('/'); 

	$post_type = get_post_type( $post->ID ); echo $post_type; 

	echo ('">'); 

	echo ('<span style="text-transform: uppercase">');

	$post_type = get_post_type( $post->ID ); echo $post_type;
	echo('</span></a>');
?>

thanks!
