严格标准：公共静态函数：错误

Question

我有点问题。我刚刚将我的专用服务器更新到 PHP 5.4.17，似乎遇到了一些严格的标准问题。由于我们的服务器和脚本处理错误的独特方式，我无法隐藏错误，并且只是将“公共函数”更改为“公共静态函数”似乎根本没有做任何事情。下面是导致错误的代码的 sn-p。任何帮助表示赞赏。

错误信息

这是一个通知，并不是真正的错误。如果您无法禁用严格通知，那么您的服务器设置很有趣......

在这部分通知之后：非静态方法 KRecord::new_record() 告诉我们 在你的类KRecord中，需要静态定义方法new_record，如：

public function new_record($fields) {

只需要静态定义：

 public static function new_record($fields) {

您表明您已将它们更改为静态，但您在问题中的代码并未表明该更改。
