Example 5-21. upper
`<?php $smarty = new Smarty; $smarty->assign('articleTitle', "If Strike isn't Settled Quickly it may Last a While."); $smarty->display('index.tpl'); ?>`
where index.tpl is:
    {$articleTitle}
    {$articleTitle|upper}
This will output:
    If Strike isn't Settled Quickly it may Last a While.
    IF STRIKE ISN'T SETTLED QUICKLY IT MAY LAST A WHILE.
