CI_Exceptions错误

Question

我在主页上遇到以下错误。请帮我解决此错误

Strict Standards: Declaration of AI_Exceptions::show_404() should be compatible with CI_Exceptions::show_404($page = ) in /home/enjoythe/public_html/application/libraries/AI_Exceptions.php on line 32

AI_Exceptions.php文件包含

/**

class AI_Exceptions extends CI_Exceptions
{
    /**
     * Constructor
     */
    function __construct()
    {
        //call the parent class constructor
        parent::__construct();

        //Log the loading of this class
        log_message('debug', "AgriyaIgniter Exceptions Class Initialized");
    }

    function show_404($page)
    {
        $config =& get_config();
        header('Location: ' . $config['base_url'] . $config['index_page'] . 'pagenotfound/' . $page);
        exit;
    }
}
// END AI_Exceptions Class

为$ page添加默认值

function show_404($page = '')
{
    $config =& get_config();
    header('Location: ' . $config['base_url'] . $config['index_page'] . 'pagenotfound/' . $page);
    exit;
}
