Question

I have this code here:

<?php 

$url = "http://otter.topsy.com/search.json?q=debt%20management&window=a";
$jsonfile = file_get_contents($url);
$obj = json_decode($jsonfile);

echo $obj->response[0]->list[0]->trackback_permalink;

?>

*Note: I have taken my API key out of the URL.

However, it returns this:

Notice: Trying to get property of non-object in
C:\xampp\htdocs\topsyAPI\index.php on line 23

Notice: Trying to get property of non-object in
C:\xampp\htdocs\topsyAPI\index.php on line 23

Notice: Trying to get property of non-object in
C:\xampp\htdocs\topsyAPI\index.php on line 23

I tried using the true parameter on json_decode and it’s still not working.

This is the first time i’ve worked with an API and JSON, so I am very much new to it.. Could someone help me out please?

Answer 1

As I wrote in the comments, response is an object, not an array. The reference should be to

$obj->response->list[0]->trackback_permalink

Not

$obj->response[0]->list[0]->trackback_permalink
