我试图限制一些国家，并且它完全重定向到受限制的国家/地区用户。但是，当用户不是来自Restrict国家/地区时，我的网站正在加载，但网站顶部显示以下错误消息。
Strict standards: Non-static method CountryDetector::countryMatches() should not be called statically in C:\wamp\www\final\country\CountryDetector.class.php on line 61
我在我的index.php文件中调用这个类：
<?php
include('/country/CountryDetector.class.php');
CountryDetector::redirect("DE", "http://google.com");
?>
我正在使用的类库是：
<?php
include("CountryDetector.interface.php");
/**
* Class that lookup's for a country code then it redirects (include files, or callbacks) the user to desired content you want.
* The function of this class is like Google that redirects users from countries that support google
* e.g. in UK when you enter google.com you will be redirected to google.co.uk and this is excatly
* what you can do with CountryDetector
*
* This class is builded in static context for purpose of best usage

答案 0 :(得分：0)
你的方法是countryMatches没有静态声明，只是private static function countryMatches($country, $except)
