How to retrieve the slug of current page?

Question

I am trying to retrieve the slug of the current wordpress page outside the loop. The title of the page returns with wp_title () but how can I get the slug?

<li><a href="/slug-of-current-page/"><?php wp_title("",true); ?></a></li>

Answer 1

use global variable $post.

<?php 
    global $post;
    $post_slug=$post->post_name;
?>

Answer 2

You can use get_permalink() outside of the loop, that should do what you need.

Answer 3

An alternative to Arvind's solution is to use the sanitize_title function:

In this specific case:

<li><a href="/<?php $slug = sanitize_title( get_the_title(), $fallback_title ); 
echo $slug; ?>/"><?php wp_title("",true); ?></a></li>
