我目前正在尝试使用Kirby CMS的一些东西。
现在我正在尝试用一些图片构建一个简单的博客，我想要实现的是，博客文章中的第一张也是唯一的第一张图片，与文章的简短摘录一起显示在文章概述中.
所以我使用了 kirby 的 $page->images() 函数，它为我提供了帖子中所有图片的 url。但我只想要第一张照片！因为我找不到任何记录的选项来使用 kirby 函数执行此操作，所以我尝试在 php 中执行此操作。
我发现了什么：
-kirby 返回一个对象。
-我找不到任何 php 方法从对象中切出某些东西，所以我尝试将其转换为数组：
$pictureArray = (array) $article->images();
- 然后我尝试使用 array_slice，它返回了奇怪的结果，所以我仔细查看了我的数组。print_r($pictureArray); 返回这个：

有谁知道这是什么吗？我的意思是图片网址在那里，但是这些东西到底是从哪里来的？当我尝试回显 $page->images() 函数时，它只返回图像 url 而不是整篇文章。
有人可以帮忙吗？也许甚至可以通过仅 kirby 函数而不是 php 来实现这一点？
