Get single field from PHP JSON response
Question
I have an api to get vehicle data by registration mark.
The JSON result is showing a long list of all fields. I am wanting to just get one or two fields. For example Make and Model
$curl = curl_init();
$ApiKey = "xxxx-xxxx-xxxx-xxx";
$url = "https://uk1.ukvehicledata.co.uk/api/datapackage/%s?v=2&api_nullitems=1&key_vrm=%s&auth_apikey=%s";
$url = sprintf($url, "VehicleData", "AK18OKJ", $ApiKey);
curl_setopt_array($curl, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_MAXREDIRS => 10,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET"
));
$response = curl_exec($curl);
$error = curl_error($curl);
curl_close($curl);
echo"<pre>";
var_dump(json_decode($response, true));
echo"</pre>";
Here is the raw JSON i get back

First you have to decode your JSON-String into an associative array. Here you can read about it: https://www.w3schools.com/php/php_arrays_associative.asp
$assoc_array = json_decode($response, true); // set second parameter to true to get an associative array as return value
Then you can access it this way:
echo $assoc_array['Response']['DataItems']['ClassificationDetails']['Smmt']['Make'];
// returns AUDI
This code displays the array readable for you and can help you finding the right keys:
echo '<pre>';
print_r( $assoc_array );
echo '</pre>';

// first decode the json into an array
$data = json_decode($response, true);
// next, grab the Dvla data from that array if it exists to make the rest simpler
$dvla = isset($data['Response']['DataItems']['ClassificationDetails']['Dvla']) ? $data['Response']['DataItems']['ClassificationDetails']['Dvla'] : [];
// now, grab the make and model from that Dvla data if it exists
$make = isset($dvla['Make']) ? $dvla['Make'] : null;
$model = isset($dvla['Model']) ? $dvla['Model'] : null;
echo "Make: $make, Model: $model";
Prints Make: AUDI, Model: RS 4 TFSI QUATTRO AUTO
