JSON Response PHP Problem

Developing with LIFX
#1

Hey guys,

I’m having an issue with the API JSON response at present. I can hit the API endpoint and a response is returned, but beyond that nothing works. When I try to decode that any attempts to read the object/array returns nothing.

Here’s my code (mostly taken from the example):

$link = "https://api.lifx.com/v1/lights/id:d073d50395f7";  
$authToken = "xxx";
$ch = curl_init($link);
$headers = array('Authorization: Bearer ' . $authToken);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);

$response is:

[{"id":"d073d50395f7","uuid":"02a0e18c-8512-413b-a80d-278892797049","label":"Bedroom","connected":false,"power":"on","color":{"hue":0.0,"saturation":0.0,"kelvin":3500},"brightness":1.0,"group":{"id":"7378a9c5e8577085ae7ea66c28efd4dc","name":"My Room"},"location":{"id":"a198da09c4cd960a7756063707602672","name":"My Home"},"product":{"name":"Original 1000","identifier":"lifx_original_a21","company":"LIFX","capabilities":{"has_color":true,"has_variable_color_temp":true}},"last_seen":"2016-09-18T04:31:25.000+01:00","seconds_since_seen":36665.582616875}]

Then decode:

$json = json_decode($response);

From this point, any attempt to read values from $json fails. print_r just returns 1.

Any ideas what’s going wrong? I’ve tried this on two separate servers, different PHP versions and nothing works :frowning:

I have hit this issue a couple of times. It’s a very simple solution:

$json = json_decode($response, true);

Including that ‘true’ forces the resulting array to be associative (or something) so that you can access the elements using their names.

Ended up getting this working last night with help from Reddit.

Turns out curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

was missing from the code. Once that was added in I was able to work from there. Thanks all!
