Sådan benyttes komponenten Server klassen

Først skal du inkludere den fil der beskriver komponenten, som en klasse fil

<? require_once(HTML_PACKAGE_PATH.'/Server.php'); ?>

Dernæst kan du enten benytte komponenten som et taglib (statiske metoder):

<? Server::display($param1, $param2, $param3, ...); ?>

eller du kan lave en instance af komponenten og benytte metoderne direkte:

<? $object = new Server($param1, $param2, $param3, ...); print $object->getHtml(); ?>
