PHP course_modinfo::get_section_info方法代碼示例

    /**
     * If dynamic data for this course-module is not yet available, gets it.

     * that can be modified by modules (have a set_xxx method).

     * runtime based on the current user. Primarily this concerns whether the user can access
     * the module or not.

     * be called (if it exists).
