How is oauth_signature twitter api v2 formed?

Question

PHP

I want to publish a post through the method /2/tweets, I did everything fine, but I don’t understand how to generate oauth_signature

function buildBaseString($baseURI, $method, $params) {
    $r = array();
    ksort($params);
    foreach($params as $key=>$value){
        $r[] = "$key=" . rawurlencode($value);
    }
    return $method."&" . rawurlencode($baseURI) . '&' . rawurlencode(implode('&', $r));
}

function buildAuthorizationHeader($oauth) {
    $r = 'Authorization: OAuth ';
    $values = array();
    foreach($oauth as $key=>$value)
        $values[] = "$key=\"" . rawurlencode($value) . "\"";
    $r .= implode(', ', $values);
    return $r;
}

$url = "https://api.twitter.com/2/tweets";

$oauth_access_token = "токен";
$oauth_access_token_secret = "секрет токен";
$consumer_key = "consumer_key токен";
$consumer_secret = "consumer секрет токен";

$oauth = array(
'oauth_consumer_key' => $consumer_key,
'oauth_token' => $oauth_access_token,
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_timestamp' => time(),
'oauth_nonce' => time(),
'oauth_version' => '1.0');

// Тут что-то не правильно, не правильный oauth_signature формирую
$base_info = buildBaseString($url, 'POST', $oauth);
$composite_key = rawurlencode($consumer_secret) . '&' . rawurlencode($oauth_access_token_secret);
$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;

// Публикация поста
$array = array(
    'text' => 'test new post'
);

$request = tweets('https://api.twitter.com/2/tweets', $array);
print_r($request);

$header = array(buildAuthorizationHeader($oauth), 'Content-type: application/json');

// Функция постинга твита
function tweets($url, $post) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post)); 
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}
