wordpress display post categories

To display post categories in WordPress, you can follow these steps:

1. Open the file where you want to display the post categories, such as single.php or archive.php.
2. Use the WordPress function get_the_category() to retrieve the categories associated with the post.
3. Use a foreach loop to iterate through the categories and display them as needed.
4. You can also use other functions like get_categories() or wp_list_categories() depending on your specific requirements.
