我正在尝试使用Facebook Graph API将员工Facebook个人资料中的详细信息导入我们的个人网站。
从以下URI获取JSON对象： https://graph.facebook.com/RDTATTOOANDPIERCING
我认为我可以简单地转换为数组并回显所需的值。但是我收到了错误。
以下是代码：
<?php
$facebook = json_decode(file_get_contents("https://graph.facebook.com/RDTATTOOANDPIERCING"));
echo $facebook["about"];
?>
如果您想查看正在呈现的来源，请输入以下网址： http://www.rdtattoopiercing.com/
提前致谢！

试试这个：
$facebook = json_decode(file_get_contents("https://graph.facebook.com/RDTATTOOANDPIERCING"), TRUE);
echo $facebook["about"];
或使用对象
$facebook->about;

问题是它返回了一个stdClass而不是一个数组，你可以通过使用var_dump($facebook)来判断，要将stdClass转换为数组，请使用get_object_vars()。
这是您的解决方案：
<?php
$facebook = get_object_vars(json_decode(file_get_contents("http://graph.facebook.com/RDTATTOOANDPIERCING")));
echo $facebook['about'];
?>
以下是转换为数组之前的var_dump：
object(stdClass)#1 (20) { ["about"]=> string(60) "Red Dragon Tattoo & Piercing is devoted to inking Cincinnati" ["checkins"]=> int(144) ["description"]=> string(509) "Red Dragon has been open since Feb. 2009, After Gabriel started constructing J began to Fill the chairs with his large following, after only a few months we brought on Chuck and Jocelyn to help with the overwhelming amount of people ready to get tattooed in the Colerain area and we've been inking up Cincinnati since then.

正如你所看到的，它以object（stdClass）开头而不是它应该是一个数组，所以添加代码get_object_vars()将返回一个数组格式而不是stdClass，正如你可以从var_dump看到的那样。 ：
array(20) { ["about"]=> string(60) "Red Dragon Tattoo & Piercing is devoted to inking Cincinnati" ["checkins"]=> int(144) ["description"]=> string(509) "Red Dragon has been open since Feb. 2009, After Gabriel started constructing J began to Fill the chairs with his large following, after only a few months we brought on Chuck and Jocelyn to help with the overwhelming amount of people ready to get tattooed in the Colerain area and we've been inking up Cincinnati since then.
