我在尝试打开我的网站时收到以下错误。

致命错误：带有非常量操作数的“break”运算符不再支持............

我认为这一定是 PHP 版本错误，但我似乎无法找出以下代码中的问题

$search_code = '';
        $b = 2;
        foreach ($categories as $category) {
            switch($category) {

                $search_code = 'bullion';
                    break $b;
                case 2:
