    The get_theme_feature_list() function in WordPress is designed to retrieve a list of WordPress theme features, often referred to as theme tags. These theme tags are useful for understanding the capabilities and special features that themes offer. Here's a detailed explanation of its functionality and a sample usage:

    Function:

    • Name: get_theme_feature_list
    • Purpose: Retrieves a list of WordPress theme features (theme tags).
    • Return Type: array

    Parameters:

    • $api (boolean, optional): This parameter determines whether the function should try to fetch the theme tags from the WordPress.org API. By default, it is set to true.
      • Type: bool
      • Default Value: true

    Return:

    • The function returns an array. This array consists of features categorized by certain criteria, with translations of these features keyed by their slug.

    Description:

    When you call get_theme_feature_list(), it fetches an array of theme features. If the $api parameter is set to true (which is the default behavior), it attempts to retrieve the latest theme tags from the WordPress.org API. This is particularly useful for theme developers and users who want to understand what features are currently supported or recognized in the WordPress ecosystem.

    If the $api parameter is set to false, it will return the theme features available locally without attempting to fetch updates from the WordPress.org API. This might be used in scenarios where a quick or offline reference to theme features is needed, or in a controlled environment where external API calls are restricted or unnecessary.

    Sample Usage:

    // Example 1: Get theme features using default settings (fetch from API)
    $theme_features = get_theme_feature_list();
    print_r($theme_features);
    
    // Example 2: Get theme features without fetching from the API
    $theme_features_local = get_theme_feature_list(false);
    print_r($theme_features_local);
    

    In these examples, print_r is used to display the structure of the returned array, which will give you a detailed view of the available theme features and their respective categories. This can be particularly useful for theme development or analysis purposes.
