Code example (fix)

            $renewed = 0;

            // Refresh the token if possible, else fetch a new one.
            if ( $client->getRefreshToken() ) {
                $client->fetchAccessTokenWithRefreshToken( $client->getRefreshToken() );
                $renewed = 1;
            } else {
                // Request authorization from the user.
                $authUrl = $client->createAuthUrl();
                printf( "Open the following link in your browser:\n%s\n", $authUrl );
                print 'Enter verification code: ';
                $authCode = trim( fgets( STDIN ) );

                // Exchange authorization code for an access token.
                $accessToken = $client->fetchAccessTokenWithAuthCode( $authCode );
                $client->setAccessToken( $accessToken );

                // Check to see if there was an error.
                if ( array_key_exists( 'error', $accessToken ) ) {
                    throw new Exception( join( ', ', $accessToken ) );
                }
            }

            if (! $renewed) {
                // Save the token to a file.
                if ( ! file_exists( dirname( $tokenPath ) ) ) {
                    $mkdir_res = mkdir( dirname( $tokenPath ), 0700, true );

                    if ( empty( $mkdir_res ) ) {
                        throw new Exception( "Cannot create parent directory for file: " . $tokenPath );
                    }
                }

                $save_res = file_put_contents( $tokenPath, json_encode( $client->getAccessToken() ), LOCK_EX );

                if ( empty( $save_res ) ) {
                    throw new Exception( "Cannot save file: " . $tokenPath );
