E' usato per contare il numero di frasi contenute in una variabile.
Example 5.6. count_sentences
<?php
$smarty = new Smarty;
$smarty->assign('articleTitle', 'Two Soviet Ships Collide - One Dies. Enraged Cow Injures Farmer with Axe.');
$smarty->display('index.tpl');
?>
Dove index.tpl è:
{$articleTitle}
{$articleTitle|count_sentences}
Questo stamperà:
Two Soviet Ships Collide - One Dies. Enraged Cow Injures Farmer with Axe. 2
