示例1: get
/**
* Returns coursecat object for requested category
*
* If category is not visible to user it is treated as non existing
* unless $alwaysreturnhidden is set to true
*
* If id is 0, the pseudo object for root category is returned (convenient
* for calling other functions such as get_children())
*
* @param int $id category id
* @param int $strictness whether to throw an exception (MUST_EXIST) or
* return null (IGNORE_MISSING) in case the category is not found or
* not visible to current user
* @param bool $alwaysreturnhidden set to true if you want an object to be
* returned even if this category is not visible to the current user
* (category is hidden and user does not have
* 'moodle/category:viewhiddencategories' capability). Use with care!
* @return null|coursecat
* @throws moodle_exception
