How to show post categories in Wordpress?

问题

i'm making a theme in WP but i can't find a way to show the categories of a single post, i want to display the categories that have a single post not all categories, i was using...

<?php $args = array ('hide_empty' => 0,'title_li' => false,'style' => 'none',);wp_list_categories($args);?>

But this is showing all categories and i don't need this. I'm new in this and i'm gonna be happy if somebody can help me :D

Before i forget, sorry if my english is bad.

You can get all categories for particular post using below code

$terms = wp_get_post_terms($post_id,'category');
foreach ($terms as $term) {
    echo $cat_name = $term->name;
    echo "<br>";
    echo $cat_id = $term->term_id;    
}

If somebody need it, is <?php the_category(',');?>
