E' usato per contare il numero di parole contenute in una variabile.
Example 5.7. count_words
<?php
$smarty = new Smarty;
$smarty->assign('articleTitle', 'Dealers Will Hear Car Talk at Noon.');
$smarty->display('index.tpl');
?>
Dove index.tpl è:
{$articleTitle}
{$articleTitle|count_words}
Questo stamperà:
Dealers Will Hear Car Talk at Noon. 7
