Data from geoJSON API call in Larvel 5.8 - laravel

Question

I am trying to retrieve data from the weather.gov API - it returns the format in geoJSON and I am not sure how to actually get the data I want from it.
If I am using the weatherbit.io API, I have no issues as it returns JSON format in which I can pull from rather easily.
I am using GuzzleHTTP to make the API call.
I am playing around with learning APIs and I have an interest in weather so I figured I would work on an application in which I could pull information from the local weather station and output it in to readable format for users in a table.
The code I am currently using is:
$api_call = https://api.weather.xxx/points/LAT,LON;
$client = new \GuzzleHttp\Client();
$request = $client->get($api_call);
if ($request->getStatusCode() == 200) {
$weatherRequest = $request->getBody();
$requestedWeather = json_decode($weatherRequest);
$currentweather = $requestedWeather; ** THIS IS WHERE I NEED HELP ***
}
return $currentweather;
});
return view('currentweather', ["currentweather" => $currentweather]);
When I am returning $currentweather and var_dump it to the view, it gives me all the geoJSON data but I don't know how to correctly iterate through the data to pull the information I need.
When I pull from another API it gives a different JSON format which I can just pull like so:
$api_call = https://api.weatherbit.xx/v2.0/current?
$client = new \GuzzleHttp\Client();
$request = $client->get($api_call);
if ($request->getStatusCode() == 200) {
$weatherRequest = $request->getBody();
$requestedWeather = json_decode($weatherRequest);
$currentweather = $requestedWeather->data;
}
return $currentweather;
});
return view('currentweather', ["currentweather" => $currentweather]);
}
And when I use $currentweather in my view I can pull any data I need with the object string name. I am not sure how to pull the data when it's leading off with the #Context tag.
The data I want lies in the "properties" part of the geoJSON array and I just can't seem to figure out how to get that in the way I am currently using.
This is my geoJSON array return:
{ "#context": [ "https://raw.githubusercontent.xxx/geojson/geojson-ld/master/contexts/geojson-base.jsonld", { "wx": "https://api.weather.xxx/ontology#", "s": "https://schema.org/", "geo": "http://www.opengis.xxx/ont/geosparql#", "unit": "http://codes.wmo.xxx/common/unit/", "#vocab": "https://api.weather.xxx/ontology#", "geometry":

Thanks for your help!

Any member of the JSON object can be accessed via the same name on the object returned by json_decode. Your weatherbit example $requestedWeather->data works because everything is in a member called data. So... $requestedWeather->properties will get you what you want from the weather.gov API.
You can also pass true as a second argument to json_decode to get back a plain PHP array instead.
$requestedWeather = json_decode($weatherRequest, true);
var_dump($requestedWeather['properties']);
This is often recommended because JSON allows member names that are not valid PHP object property names (e.g., names containing hyphens).
