how to send json to php?

Question

PHP

Happy New Year everyone)

There is JSON and PHP code.

The JSON sends the required content on Monday and creates the item, while PHP doesn't work.
Where did I make a mistake in trying to rewrite the working JSON? Thanks =)

JSON:

const body = {
              query: `
                mutation {
                  create_item (board_id: 748486084, group_id: "new_group88144", item_name: "new item") {
                    id
                  }
                }
              `,
              variables: {
                boardId: 748486084,
                groupId: "new_group88144",
                itemName: "new item",
              }
            }

            fetch('http://api.monday.com/v2/', {
                method: 'POST',
                headers: {
                  'Content-Type': 'application/json',
                  'Authorization': 'TOKEN',
                },
                body: JSON.stringify(body),
              })
              .then(response => response.json());

PHP:

$url = 'http://api.monday.com/v2/';
            $dataquery = '"Authorizationl:TOKEN" query: `mutation { create_item (board_id: 748486084, group_id: "new_group88144", item_name: "new item") {id}}`';

            $options = array(
                'http' => array(
                    'header'  => "Content-type: application/json",
                    'method'  => 'POST',
                    'body' => http_build_query($dataquery),
                )
            );
            $context  = stream_context_create($options);
            $result = file_get_contents($url, false, $context);
            if ($result === FALSE) { /* Handle error */ }

            echo($result);
            var_dump($result);

In general, I re-read the API and the solution was as follows

$token = 'TOKEN';
$apiUrl = 'https://api.monday.com/v2';
$headers = ['Content-Type: application/json', 'Authorization: ' . $token];

$query = 'mutation{ create_item (board_id:id, group_id: "group", item_name:"name") { id } }';
$data = @file_get_contents($apiUrl, false, stream_context_create([
 'http' => [
 'method' => 'POST',
 'header' => $headers,
 'content' => json_encode(['query' => $query]),
 ]
]));
$responseContent = json_decode($data, true);

echo json_encode($responseContent);
