Which Function Do You Use to Register a New Post Type in WordPress?

When registering a new post type in WordPress, you have a few options. The first option is to use the register_post_type function.

This function registers the post type with the WordPress Codex and provides some basic registration options.

The second option is to use the wp_register_post_type function. This function registers the post type with WordPressmu and provides more advanced registration options.

Both functions provide the same basic options: name, slug, description, and required fields.

The third option is to use the add_action function to register the post type. This function allows you to add the post type to a specific plugin or theme.
