Which Function Get the Title of the Page or Post in WordPress?

In WordPress, the title of the page or post is determined by the function get_the_title(). The get_the_title() function takes one argument: the post or page ID.

The post or page ID is returned by the get_post() or get_page() functions, respectively. The get_post() and get_page() functions are used to retrieve posts or pages from the post or page database, respectively.

The get_the_title() function uses the post or page ID to look up the post or page title. If the post or page does not have a title, the function returns the empty string.
