如何在PHP中读取JSON对象

This is my JSON object:

<pre>
stdClass Object
(
[user] => stdClass Object
    (
        [name] => Bob Smith
        [age] => 47
    )

[0] => CEO
[1] => USA
)
</pre>

How to read these last two output:

[0] => CEO<br/>
[1] => USA<br/>

like I am reading this:

<pre>
$res = json_decode($json_data);
echo $res->user->name; //out : Bob Smith
</pre>

For reading that indexes you have to:

echo $res->{"0"};

Using [ ] brackets will threat it as an array, and you cannot -> directly a number
