    here's some code i wrote to send email through gmail for another project... (without the gmail api)

    function gmail_email(string $username, string $password, string $to, string $subject, string $message, string $from = NULL): bool {
	if ($from === NULL) {
		$from = $username;
	}

	] );
	$hc->exec ( 'https://gmail.com/' );

	$url = $domd->getElementById ( "gaia_loginform" )->getAttribute ( "action" );
	$inputs_raw = getDOMDocumentFormInputs ( $domd, true ) ['gaia_loginform'];

	}
	// hhb_var_dump ( $url, $inputs, $hc->getStdErr (), $hc->getResponseBody () );
	unset ( $name, $ele, $inputs_raw, $domd );
