PHP API Quickstart tutorial example 3, as-written doesn't work due to json_encode being run on an already encoded JSON object
The last example described in the PHP API Quickstart tutorial here: https://support.monday.com/hc/en-us/articles/360013465659-API-Quickstart-Tutorial-PHP does not work out of the box.
This example indicates that variables should be passed in as part of the request in a separate vars object passed alongside the query object; modified ever so slightly to work with text columns

$token = 'tokenstring';
$apiUrl = 'https://api.monday.com/v2';
$headers = ['Content-Type: application/json', 'Authorization: ' . $token];
$query = 'mutation ($myItemName: String!, $columnVals: JSON!) { create_item (board_id:XXXXXXXXX, item_name:$myItemName, column_values:$columnVals) { id } }';
$vars = ['myItemName' => 'Hello world!',
'columnVals' => json_encode([
'long_text5' => ['text' => '0400000000'],
'phone3' => ['text' => 'asd']
])];
$test_encoded = json_encode(['query' => $query, 'variables' => $vars]);
$data = @file_get_co
