Question

我正在开发一个CMS，它使用yaml文件来操纵主题。我的问题是我需要列出菜单的子菜单。例如，我可以访问“标题”菜单，在其中可以更改其内容，但是在“标题”中有子菜单，我只想列出它们。

我有可以搜索的服务

由于数据是数组，如何在屏幕上打印？

public function query() {

    /* @var $request Request */
    $request = app('request');

    /* @var $website Site */
    $website = $request->route('website');
    $menu = $request->route('submenu');

    // Carega configurações do site
    $this->service->loadWebsite($website->slug);
    /*
    - title: menu1
      submenu:
       - title: submenu 1.1
       - title: submenu 1.2
    - title: menu2
      submenu:
       - title: submenu 2.1
    */


    /*
    - title: menu1
    - title: - submenu 1.1
    - title: - submenu 1.2
    - title: menu2
    - title: - submenu 2.1
    */
    // puxa os menus da configuração do site
    $menus = $this->service->getWebsiteConfig($website->slug, 'menu.' . $menu . '.menu');

    dd($menus);
    return $menus;
}

服务

 protected function toWebisteMenuItemCollection(string $menu, array $rows) {
    return collect($rows)->map(function (array $data, string $key) use ($menu) {
        $data['id'] = $menu . '.' . $key;
        if(isset($data['submenu']) && is_array($data['submenu'])) {
            $data['submenu'] = $this->toWebisteMenuItemCollection($data['id'], $data['submenu']);
        }

        return new WebsiteMenuItem($data);
    });
}

dd（$ menu）

Answer 1

var_dump（$ array_youd_like_to_print）将为您提供数组的所有内容（甚至嵌套）。

如果可以解决您的问题，则可以按原样使用它，或者使用它来查找您要查找的值（以及如何在数组中访问它）并打印出来。

我需要显示一个数组的数组
