    The get_the_comments_navigation() function in WordPress is designed to provide navigation for moving between sets of comments. This is particularly useful when you have a large number of comments split into multiple pages on a post or page. Here's a detailed explanation of the function and how it can be used:

    Function Signature:

    get_the_comments_navigation( array $args = array() ): string
    

    Function Description:

    • Purpose: This function retrieves navigation links (previous and next) for the comment section of a post or page. It's used when there are enough comments to necessitate splitting them across multiple pages.
    • Return Value: It returns a string containing the markup for the comments navigation links.

    Parameters:

    • $args (array - Optional): This parameter allows you to customize the comments navigation. It's an associative array where you can specify several options. The default value is an empty array. The following are the key options you can set in the $args array:
      • prev_text (string): The anchor text to display for the previous comments link. Default is 'Older comments'.
      • next_text (string): The anchor text to display for the next comments link. Default is 'Newer comments'.
      • screen_reader_text (string): Text used for screen readers. It describes the navigation element. Default is 'Comments navigation'.
      • aria_label (string): ARIA label text for the navigation element, improving accessibility. Default is 'Comments'.
      • class (string): Custom class for styling the navigation element. Default is 'comment-navigation'.

    Default Values:

    • If no $args array is provided, or if specific keys are not set in the array, the function will use its default values as mentioned above.

    Return:

    • The function returns a string containing the HTML markup for the comments navigation links. This string can be directly echoed in a WordPress template to display the navigation.

    Sample Usage:

    // Basic usage without any custom arguments
    echo get_the_comments_navigation();
    
    // With custom arguments
    echo get_the_comments_navigation( array(
        'prev_text' => 'Previous Comments',
        'next_text' => 'Next Comments',
        'screen_reader_text' => 'Navigate through the comments',
        'aria_label' => 'Comment navigation',
        'class' => 'my-custom-class'
    ) );
    

    In the sample usage, the first example uses the function in its simplest form with default values. The second example demonstrates how to customize the navigation links, screen reader text, ARIA label, and the CSS class for styling.
