如何与twitter的API的JSON返回正确交互？

Question

I'm using the Twitter API (version 1.1) and am trying to get a specific variable from the JSON return via PHP. $mentions is the returned json_decode() value of a GET statuses/mentions_timeline request.

I have the following PHP:

foreach($mentions as $mention) {
    echo '<pre>' . print_r($mention) . "</pre><br>";
}

This works as expected, however when I add ['created_at'] to $mention I get:

Fatal error: Cannot use object of type stdClass as array

Expected return as per the twitter docs:

[ // mentions
  { // mention
    "created_at": "Mon Sep 03 13:24:14 +0000 2012"
  }
]

This is an example of what's returned with print_r($mention) (inside the loop):

stdClass Object (
    [created_at] => Sat Apr 06 14:56:36 +0000 2013
)

Just what is this stdClass and how do I interact with it, if possible?

Answer 1

Use

$mentions = json_decode($data, true)

If you look in the docs, you will notice that there is assoc parameter if you want to get associative array instead of an object.

Otherwise you can access object properties with $mention->created_at
