I am trying to check the value of 'state' but I cant seem to figure out how to reference that value. I have tried: ($result is the variable where the array is located)
$result['body']['state']
$result['state']
$body['state']
None of those work, so can anyone tell me how to reference the key 'state' in that mess up there? I am usually pretty good with PHP but for some reason I can not figure this one out.
Thanks for your help.
Edit
I have formatted the response so its easier to ready but I am stuck on selecting the [1] href value. If I base it on the previous example I would use
$result['body']->link but how do I get past that to the specific href in [1]?

Answer 1

The formatting doesn't help, but it looks like $result['body']->state will get you what you're looking for.
You were closest with your first attempt, $result['body']['state'], however $result['body'] is an object, and so you need to use -> to access its properties.
