Sådan benyttes komponenten Label klassen
Først skal du inkludere den fil der beskriver komponenten, som en klasse fil
<? require_once(HTML_PACKAGE_PATH.'/Label.php'); ?>
Dernæst kan du enten benytte komponenten som et taglib (statiske metoder):
<? Label::display($param1, $param2, $param3, ...); ?>
eller du kan lave en instance af komponenten og benytte metoderne direkte:
<? $object = new Label($param1, $param2, $param3, ...); print $object->getHtml(); ?>
Sådan vises komponenten Label klassen
