来自 Imgur 专辑的随机图像生成器答案

【问题描述】：

我希望使用 PHP 创建一个 Apache 站点，这样每次有人指向它时，它都会从先前创建的 Imgur 相册中抓取一张随机图像，其中包含图像，并在不离开网站的情况下显示加载的图像。我想我需要使用 Imgur API 来用 php 做这种事情，但我不知道从哪里开始。有谁知道我怎么能做到这一点？

我使用数组制作了这个 javascript 替代方案，但这仅获取 javascript 代码中列出的图像，我想利用 Imgur API 并自动从 Imgur 相册中获取所有图像的 URL 并随机选择一个显示每个用户加载网页的时间。

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Random</title>

<script type="text/javascript">
function randomlinks(){
    var myrandom=Math.round(Math.random()*263)
    var links=new Array()
links[0]="http://i.imgur.com/blablablabla.jpg"


    window.location=links[myrandom]

}
</script>

  </head>
  <body onload="randomlinks()">

  </body>
</html>

【解决方案1】：

这是使用imgur api从相册返回的json，您可以在PHP中将此json转换为数组，然后使用array_rand()随机选择一个：

作为 $json 来自 imgur 服务器的字符串，此代码将收集一个随机链接：

$array=json_decode($json);

$links = array();

foreach($array->data->images as $img)
$links[]=$img->link;

echo $links[array_rand($links)];

【讨论】：

如何将其解析为 PHP？ json_decode() 也许？
准确地说，json_decode 从 json 字符串中创建了一个数组。
从那以后我有点迷路了。我知道我必须从数组中获取某个值，但我自己对 JSON 并不熟悉。
这样的东西有帮助吗？ $jsonArr = json_decode($str, TRUE); $rand_array_key = array_rand($jsonArr); echo $jsonArr[$rand_array_key]['id'];
非常感谢，所以 $json 将是来自 imgur api 服务器的 url 字符串？
