  • In your codes use require_once to require a php file, then you can call all functions in the file directly.

    Note: If the function belongs to a class definition, a object must be create to use the function. Maybe you can use a global object such as $post, $comment, $wpdb, etc.

    I am a beginner. Hope it helps.
