Writer, Sample code, tutorial

Sådan benyttes komponenten Writer klassen

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

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

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

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

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

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