我在新项目中使用旧Laravel项目的布局文件。 但是当我输入layouts / app.php代码时，出现了此错误：
“调用未定义的函数getOption（）”
layouts / app.php文件代码：

我使用的数据库与我先前项目中使用的数据库相似 因此，在新数据库中，以前的数据库中存在着所有实例（例如them_color）
functions.php代码：

} else {

}
}
// If session is set then get config option from session
// otherwise get from database directly
$options = \Session::get('options');
if (!is_null($options)) {
if (array_key_exists($option, $options)) {
return $options[$option];
}
return null;
}
// Check if app is installed?
