There is a built-in class Date Time in PHP, and maybe many friends don't know much about this class. Let's talk about this class first.

The DateTime class can help us read, write, compare, or calculate dates and times. Of course, in addition to DATETIME, there are many date and time-related functions in PHP, but it provides a good object-oriented interface for most common uses. It can handle the time zone, but this is outside the scope of this brief introduction.

If we want to start using DateTime, we need to use the createFromFormat () factory method to convert the original date and time string to an object, or execute a new DateTime to get the current date and time. Use the format () method to convert the date time back to the string used for the output.

Using the DateInterval class, you can use DateTime for calculations. DateTime has methods like add () and sub (), which take DateInterval as parameters. Don't write code that expects the same number of seconds every day. Daylight saving time and time zone changes break this assumption. Use date intervals instead. To calculate the date difference, use the diff () method. It will return the new DateInterval, which is very easy to display.
