By the way, let me introduce to you the use of PHP date/time:

We can use these functions of PHP date/time to obtain the date and time of the server running PHP. We can also use these Functions format dates and times into strings in different formats.

Date and time information is stored as 64-bit numbers internally in PHP, which can cover 292 billion years before and after the current time. This range is wide enough to meet the actual needs of existing applications.

Note:

It should be noted that these functions are dependent on the locale settings of the server, so when using them, daylight saving time must be considered (for example: use $date = strtotime( ' 7 days', $date) instead of $date = 7*24*60*60) and leap year situations.

Finally, if you think this series of articles is of some help to you, please feel free to save them!
