Php 比较smarty中的两个日期
我有两个日期,分别是02-Dec-14和17-Dec-14,我想用smarty比较这两个日期 我如何比较这两个日期?请帮忙 提前谢谢Php 比较smarty中的两个日期,php,date,smarty,Php,Date,Smarty,我有两个日期,分别是02-Dec-14和17-Dec-14,我想用smarty比较这两个日期 我如何比较这两个日期?请帮忙 提前谢谢 <?php $d = '02-Dec-14'; $e = '17-Dec-14'; $t1 = strtotime($d); $t2 = strtotime($e); /* // Test if it works. if ($t2 > $t1) { echo 'second is greater'; } */ 在Smarty中,您可以比较
<?php
$d = '02-Dec-14';
$e = '17-Dec-14';
$t1 = strtotime($d);
$t2 = strtotime($e);
/*
// Test if it works.
if ($t2 > $t1) {
echo 'second is greater';
}
*/
在Smarty中,您可以比较:
{if $date_one < $date_rwo}
...do something..
{/if}
在Smarty中,您可以比较:
{if $date_one < $date_rwo}
...do something..
{/if}
例如,如果您将这些日期指定给Smarty:
$smarty->assign('date2','02-Dec-14');
$smarty->assign('date1','17-Dec-14');
您可以在Smarty中直接使用strotime函数,例如:
{if $date1|strtotime < $date2|strtotime}
{$date1} is earlier than {$date2}
{elseif $date1|strtotime == $date2|strtotime}
Both dates are the same
{else}
{$date2} is earlier than {$date1}
{/if}

我尝试了很多方法,但都没有找到解决办法。最后我尝试了这样的方法: 在PHP中,向smarty传递2个类似的变量:
$insuranceStartDate= date("jS F Y", strtotime($startdate));
$smarty->assign('insuranceStartDate' , $insuranceStartDate);
$insuranceStartDatePlain= date("Y/m/d", strtotime($startdate));
$smarty->assign('insuranceStartDatePlain' , $insuranceStartDatePlain);
在smarty中,如下所示:
{if $insuranceStartDatePlain|date_format:'%Y/%m/%d' < '2017/09/01'}
less than - 1<sup>st</sup> Septemeber 2017
{else}
greater - {$insuranceStartDate}
{/if}
注意:要比较字符串中的日期,请在smarty中使用YYYY/MM/DD顺序
