如何从对象获取价值（php）

Question

我在以下对象中有一个变量：

echo "<pre>";
print_r($request);
echo "</pre>";
Facebook\FacebookResponse Object

            [graphVersion:protected] => v2.5
        )

    [thrownException:protected] => 
)

我需要获取并保存到数组或仅字符串：

[body:protected] => {"data":[{"access_token":"xxxxxxx","category":"Restaurant\/Cafe","category_list":[{"id":"171466272901863","name":"Late Night Restaurant"}],"name":"Karczma janka","id":"199296333814893","perms":["ADMINISTER","EDIT_PROFILE","CREATE_CONTENT","MODERATE_CONTENT","CREATE_ADS","BASIC_ADMIN"]},{"access_token":"xxxxxxx","category":"Restaurant\/Cafe","category_list":[{"id":"144722595590046","name":"Greek Restaurant"}],"name":"Jad\u0142odajnia","id":"1055846191130232","perms":["ADMINISTER","EDIT_PROFILE","CREATE_CONTENT","MODERATE_CONTENT","CREATE_ADS","BASIC_ADMIN"]}],"paging":{"cursors":{"before":"xxxxxxx","after":"xxxxxxx"}}}

我会尝试在两天内完成，但我不会出来:(我是先生。

我可以请你写一个代码来提取更高的价值吗？

非常感谢:) 现在我有了这个：

        )

)

我需要使用此数组的foreach（？）：

- access_token (eg. EAASihmm0IgUBAOVlH3gCnNvZBADYjAsgUKjGTzRHDdGyEpeTTEPCnZBP6ROFZAHp3MZCScXnmQVsfmCgpiLSKqUV1KLuIFZBBFtLTyJnEAyo36DeinzAeWOl65TDRuBP5sMdLhZCRBuXcVYTVNYHrqdZCX3lx5oKN8h4N2ZC0yHKOwZDZD),
- category (eg. Restaurant/Cafe)
- id1 (eg. 171466272901863)
- name (eg. Karczma janka),
- id2 (eg.  199296333814893)

在我的例子中，我有2家餐厅：Karczma janka和Jadłodajnia。 最后可能有任何数字（最多100个）。

我怎样才能获得这些价值？

Answer 1

我可以看到您正在输出FacebookResponse对象 所以我猜你正在写一些使用Facebook SDK的东西。

让我获取SDK的文档： https://developers.facebook.com/docs/php/FacebookResponse/5.0.0

在这些文档中，我可以看到方法getBody()，它将返回响应的主体。
