PHP Curl Json: multiple outputs - php

Question

I'm currently trying to get every title of my JSON decoded output in a variable
This is what works for me as curl
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => 'http://api.irail.be/disturbances/?format=json&lang=nl',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => '',
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => 'POST',
CURLOPT_HTTPHEADER => array(
'cache-control: no-cache',
'content-type: application/x-www-form-urlencoded'
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
// Decode JSON response and get only the data needed:
$response = json_decode($response);
$response = $response->disturbance[0];
var_dump($response);
$name = $response->title;
echo $name;
When I remove the [0] behind disturbance I am getting a blank $name. Does anyone know how I can fix this?
Thank you

You can access your objects via the keys, but "disturbance" is not a key, it is a value that the key type can take.
You need first to filter your data to get only the items with type = 'disturbance', and then you can get the titles.
Here is an example :
$response = json_decode($response);
$disturbanceItems = array_filter($response, function ($item){return $item->type == 'disturbance';});
echo $disturbanceItems[0]->title ;
