来自API调用的Print_r（）响应

So I am trying to store a value of the response but I don't know how. After I print_r() the array I get the following:

stdClass Object
(
[user_id] => id number
[access_token] => access token code
[token_type] => BEARER
)

My question is how do I for example set a variable to the access_token? Like this:

$access_token = $array['access_token'] ?

It's not an array, it's an object (see the first line of the print_r() output). To access an object property, you use ->, not []:

$access_token = $array->access_token;

You can also convert your object to an array like this

$array = json_decode(json_encode($your_object), true);
