How to make a simple PHP API handler?

Question

I wrote a basic API script in PHP using cURL - and successfully used its version on another API, this one is specifically designed to handle DNS management of a domain on DigitalOcean - and I can’t send the data?

Prelude ...

I understand that there is an accessible PHP library, I am not behind something full-featured or bloated dependencies - just something small to use locally , and first of all, to help me understand how the RESTful API works in practice a little better - educational program

Violation Code ...

function basic_api_handle($key, $method, $URI, $data) {

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Authorization: Bearer '.$key,
        'Content-Type: application/json')
    );

    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
    curl_setopt($ch, CURLOPT_URL, $URI);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

    $result = curl_exec($ch);
    if($result === false) error_log("API ERROR: Connection failure: $URI", 0);

    curl_close($ch);

    return json_decode($result, true);
}

var_dump(basic_api_handle($api_key, 'POST', 'https://api.digitalocean.com/v2/domains', array('name' => 'my-domain.tld', 'ip_address' => '1.2.3.4')));
