我想在一个网站的页脚放一个版权声明,但我认为这对于过时的年份来说是非常俗气的。

如何在php4或php5中自动更新年份?


当前回答

要使用PHP的日期函数获取当前年份,你可以像这样传入“Y”格式字符:

//Getting the current year using
//PHP's date function.

$year = date("Y");
echo $year;

上面的例子将打印出当前年份的完整的4位数字表示。

如果你只想检索2位数格式,那么你可以使用小写的“y”格式字符:

$year = date("y");
echo $year;
1
2
$year = date("y");
echo $year;

上面的代码片段将打印20而不是2020年,或者打印19而不是2019年,等等。

用M打印当前月份,用D打印日期,用Y打印年份。

<?php echo date("M D Y"); ?>
<?php
$time_now=mktime(date('h')+5,date('i')+30,date('s'));
$dateTime = date('d_m_Y   h:i:s A',$time_now);

echo $dateTime;
?>

echo date('Y')给你当前年份,这将自动更新,因为date()给我们当前日期。

以我为例,wordpress网站页脚的版权声明需要更新。

想法很简单,但涉及的步骤比预期的要多。

Open footer.php in your theme's folder. Locate copyright text, expected this to be all hard coded but found: <div id="copyright"> <?php the_field('copyright_disclaimer', 'options'); ?> </div> Now we know the year is written somewhere in WordPress admin so locate that to delete the year written text. In WP-Admin, go to Options on the left main admin menu: Then on next page go to the tab Disclaimers: and near the top you will find Copyright year: DELETE the © symbol + year + the empty space following the year, then save your page with Update button at top-right of page. With text version of year now delete, we can go and add our year that updates automatically with PHP. Go back to chunk of code in STEP 2 found in footer.php and update that to this: <div id="copyright"> &copy;<?php echo date("Y"); ?> <?php the_field('copyright_disclaimer', 'options'); ?> </div> Done! Just need to test to ensure changes have taken effect as expected.

这对很多人来说可能不是同样的情况,但是我们在相当多的客户站点中遇到过这种模式,并且认为最好在这里记录。

创建一个helper函数并调用它

getCurrentYear();

function getCurrentYear(){
    return now()->year;
}
