Required |
Default |
Description |
| 1 |
string |
No |
%b %e, %Y |
This is the format for the outputted date.
输出日期的格式。 |

This is the default date if the input is empty.
输入为空时的默认时间格式。 |
This formats a date and time into the given strftime() format.
Dates can be passed to Smarty as unix timestamps, mysql timestamps
or any string made up of month day year (parsable by strtotime).
Designers can then use date_format to have complete control of the
formatting of the date.
If the date passed to date_format is empty
and a second parameter is passed, that will be used as the date to
format.
格式化从函数strftime()获得的时间和日期。
Unix或者mysql等的时间戳记(parsable by strtotime)都可以传递到smarty。
设计者可以使用date_format完全控制日期格式。
如果传给date_format的数据是空的,将使用第二个参数作为时间格式。
Example 5-8. date_format[日期格式]
index.php:
$smarty = new Smarty;
$smarty->assign('yesterday', strtotime('-1 day'));
$smarty->display('index.tpl');
index.tpl:
{$smarty.now|date_format}
{$smarty.now|date_format:"%A, %B %e, %Y"}
{$smarty.now|date_format:"%H:%M:%S"}
{$yesterday|date_format}
{$yesterday|date_format:"%A, %B %e, %Y"}
{$yesterday|date_format:"%H:%M:%S"}
OUTPUT:
Feb 6, 2001
Tuesday, February 6, 2001
14:33:00
Feb 5, 2001
Monday, February 5, 2001

PROGRAMMERS NOTE: date_format is essentially a wrapper to PHP's strftime()
function. You may have more or less conversion specifiers available depending
on your system's strftime() function where PHP was compiled. Check your
system's manpage for a full list of valid specifiers.
程序员提示:date_format本质上是php的strftime()函数的一个包装。
当php被编译的时候你可以或多或少的依靠系统的strftime()转换有效的区分符。
可以查看系统手册的有效区分符的全表.
