That's what I do. All you need is some simple functions:

$headers = array();

addHeader($name, $value) {
	global $headers;
	$headers[$name] = $value;
	return true;
}
deleteHeader($name) {
	global $headers;
	if (array_key_exists($name, $headers)) {
		unset($headers[$name]);
	}
	return true;
}
sendHeaders() {
	global $headers;
	foreach ($headers as $name => $value) {
		header($name . ': ' . $value);
	}
	return true;
}
