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。

如果你正在使用碳PHP API扩展DateTime，你可以很容易地实现:

<？php echo Carbon::now()->年;? >

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 echo date("Y"); ?>

这段代码应该

<?php echo date("Y"); ?>

<?php date_default_timezone_set("Asia/Kolkata");?><?=date("Y");?>

你可以在页脚部分使用它来获得动态版权年份
