");
$smarty->assign("body", "More than 12 inches of snow is expected to
accumulate overnight in New York.");

{$body}

This returns the following:
Snow Expected in Northeast (14 words)

More than 12 inches of snow is expected to accumulate overnight in New York.

Formatting Dates
The date_format function is a wrapper to PHP??™s strftime() function and can convert
any date/time-formatted string that is capable of being parsed by strftime() into
some special format. Because the formatting flags are documented in the manual
and in Chapter 12, it??™s not necessary to reproduce them here. Instead, let??™s just jump
straight to a usage example:
482 CHAPTER 19 ?–  T EMPLAT I NG WITH SMARTY
$smarty = new Smarty;
$smarty->assign("title","Snow Expected in Northeast");
$smarty->assign("filed","1172345525");
$smarty->display("dateformat.tpl");
The dateformat.tpl template contains the following:
{$title}

Submitted on: {$filed|date_format:"%B %e, %Y"}
This returns the following:
Snow Expected in Northeast

variable if the application layer does not return one:
$smarty = new Smarty;
$smarty->assign("title","Snow Expected in Northeast");
$smarty->display("default.
