Remove [ and ] from excerpt

Question

I am displaying the wordpress posts on the index page with:

<?php the_excerpt(); ?>

In my functions.php file I have following code:

add_filter('excerpt_length', 'my_excerpt_length');
function my_excerpt_length($length) {
return 30; }

This works fine but it shows [...] at the end of excerpt. I want to remove these [ and ] and instead I want to show only three dots ... . How can i do that? Thanks.

Use the excerpt_more filter hook:

function mytheme_excerpt_more( $text ) {
    $text = '...';
    return $text;
}
add_filter( 'excerpt_more', 'mytheme_excerpt_more' );
