PHP GMail OAuth Kütüphane / örnek kullanma.

$options = array(
    'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER,
    'version' => '1.0',
    'consumerKey' => $THREE_LEGGED_CONSUMER_KEY,
    'callbackUrl' => getCurrentUrl(),
    'requestTokenUrl' => 'https://www.google.com/accounts/OAuthGetRequestToken',
    'userAuthorizationUrl' => 'https://www.google.com/accounts/OAuthAuthorizeToken',
    'accessTokenUrl' => 'https://www.google.com/accounts/OAuthGetAccessToken'
);

Here's the error: Parse error: syntax error, unexpected ',', expecting '(' This is from line 77: the 'requestScheme' => Zend_Oauth::REQUEST_SCHEME_HEADER, line, any ideas?

Edit: I'm using PHP 4.4.8
