This replaces all repeated spaces, newlines and tabs with a single space, or with the supplied string.
If you want to strip blocks of template text, use the built-in {strip} function.
Example 5.19. strip
<?php
$smarty->assign('articleTitle', "Grandmother of\neight makes\t hole in one.");
$smarty->display('index.tpl');
?>
Where template is:
{$articleTitle}
{$articleTitle|strip}
{$articleTitle|strip:' '}
Will output:
Grandmother of eight makes hole in one. Grandmother of eight makes hole in one. Grandmother of eight makes hole in one.
