我正在尝试使用Facebook Graph API将员工Facebook档案中的详细信息导入我们的个人网站

从以下URI获取JSON对象：

我想我可以简单地转换成数组并回显所需的值。然而，我得到了错误

代码如下：

<?php
$facebook = json_decode(file_get_contents("https://graph.facebook.com/RDTATTOOANDPIERCING"));
echo $facebook["about"];
?>

如果要查看呈现的源代码，请使用以下URL：

提前谢谢

不带第二个参数的json_decode将返回一个对象，如果希望返回数组，请添加第二个参数TRUE

试试这个：

$facebook = json_decode(file_get_contents("https://graph.facebook.com/RDTATTOOANDPIERCING"), TRUE);

echo $facebook["about"];

或者，如果不想将TRUE添加到第二个参数，则使用object

$facebook->about

试试这个：
$facebook = json_decode(file_get_contents("https://graph.facebook.com/RDTATTOOANDPIERCING"), TRUE);

echo $facebook["about"];

或者，如果不想将TRUE添加到第二个参数，则使用object
$facebook->about
问题在于它返回的是一个stdClass而不是数组，您可以通过使用var\u dump（$facebook）
来判断，要将stdClass转换为数组，请使用get\u object\u vars（）


以下是您的解决方案：
<?php
$facebook = get_object_vars(json_decode(file_get_contents("http://graph.facebook.com/RDTATTOOANDPIERCING")));
echo $facebook['about'];
?>

正如您所看到的，它以object（stdClass）开始，而应该是一个数组，因此添加代码get\u object\u vars（）
将返回一个数组格式，而不是stdClass，您可以从这个var\u dump
