php datetime类的引入
DateTimeZone::getName() is a method in PHP that is used to retrieve the name of the time zone. It returns a string that represents the name of the time zone associated with the DateTimeZone object.

For example, consider the following code:

php
$timezone = new DateTimeZone('America/New_York');
echo $timezone->getName();


The output will be:


America/New_York


In this example, the DateTimeZone object is created with the time zone identifier 'America/New_York'. The getName() method is then called on this object to get the name of the time zone, which is subsequently printed to the output.

You can use DateTimeZone::getName() to retrieve the name of the time zone associated with a DateTime or DateTimeImmutable object. Simply create a new instance of DateTimeZone based on the time zone identifier, and then call the getName() method on that object.
