Question

我使用CI框架，下面的代码是一个生成器，旨在生成类公共方法列表：

$directory = FCPATH.APPPATH.'controllers/';
$exclude = array('shell');

$filter = function ($file, $key, $iterator) use ($exclude) {
    if ($iterator->hasChildren() && !in_array($file->getFilename(), $exclude)) {
        return true;
    }
    return $file->isFile();
};

$innerIterator = new RecursiveDirectoryIterator(
    $directory,
    RecursiveDirectoryIterator::SKIP_DOTS
);

$iterator = new RecursiveIteratorIterator(
    new RecursiveCallbackFilterIterator($innerIterator, $filter)
);

foreach ($iterator as $pathname => $fileinfo) {
    if (!preg_match("/\.(php)*$/i", $pathname, $matches)) {
        continue;
    }

    $last = strrpos($pathname, '/');
    $second_last = strrpos($pathname, '/', $last - strlen($pathname) - 1);
    $last_folder_name = substr($pathname, $second_last + 1, $last - $second_last - 1);
    if($last_folder_name == 'controllers')
    {
        continue;
    }

    require_once $pathname;

    $module_name = & $last_folder_name;
    $controller_name = ucfirst($fileinfo->getBasename('.php'));

    $reflection_class = new ReflectionClass($controller_name);
}

我使用此代码取消设置变量：

unset($pathname);
unset($controller_name);
unset($reflection_class);
continue;

我似乎取消了对象，但它仍然说：

Fatal error: Cannot redeclare class Index in ...

一旦宣布了课程，你就无法宣布。如果要使用具有相同名称的多个类，请查看PHP Namespaces

如何在PHP中取消设置重复的类名？
