Using PHP you can fetch the server time, please use this code to get the current time
使用 PHP 可以获取服务器时间，请使用此代码获取当前时间
<?php echo date("D M d, Y G:i a"); ?>
You can change the Date format as per your requirement, please look here.
您可以根据需要更改日期格式，请查看此处。
Now to update the current time and date you have to refresh the element(<div>) using (JQuery Ajax) in which the date is displayed, I have provided a link which describes a way to refresh <element>in regular interval. For you it should be 1sec or 1000 miliseconds. Here is the Tutorial link.
现在要更新当前时间和日期，您必须<div>使用显示日期的 (JQuery Ajax)刷新 element( )，我提供了一个链接，该链接描述了一种<element>定期刷新的方法。对您来说，它应该是 1 秒或 1000 毫秒。这是教程链接。

PHP runs on the server, which means that you have to refresh for the code to execute it again. The best solution here is to use JavaScript as you could set a setIntervaland update an element with the new time.
PHP 在服务器上运行，这意味着您必须刷新代码才能再次执行它。这里最好的解决方案是使用 JavaScript，因为您可以设置 asetInterval并使用新时间更新元素。
