wordpress圣经 的源码 有问题吗？
wordpress 圣经 在讲Chapter 5: Extending WordPress with Plugins时，有个例子，我在试用时出现这样的问题，请高手指点：
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘copyright-notices’ not found or invalid function name in E:\xampp\htdocs\chinese\wp-includes\plugin.php on line 405：
call_user_func_array($the_[‘function’], array_slice($args, 0, (int) $the_[‘accepted_args’]))
附原码：
<?php
