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