Parsing JSON data with php - Data coming back empty

Question

I have a piece of JSON that I'm parsing with php. I need to get one of the pieces of data out of it.

Here's the output of the json when I do a print_r:

Array ( [deviceId] => 07a9727e-3fe5-4f44-9765-134388241f39 [programId] => 3895 [serviceId] => 19977 [createdAt] => 2013年12月12日T07:19:04.466Z [updatedAt] => 2013年12月12日T07:19:04.466Z [objectId] => 7TxmL2GiXq )

Here's my code trying to extract deviceId:

$objectData = json_decode($data, true);
print_r($objectData);
$deviceId = $objectData->deviceId;

$deviceId is coming back empty.

Any help would be appreciated. Thanks.

Answer 1

Do this:

$deviceId = $objectData['deviceId'];

You are using the optional second parameter TRUE in your json_decode call, which converts it into an associative array instead of an object.

Alternatively:

$objectData = json_decode($data);
$deviceId = $objectData->deviceId; // Works
