Gets the Unix timestamp.
此函數沒(méi)有參數。
Returns the Unix timestamp representing the date.
If the timestamp cannot be represented as int, a ValueError
is thrown. Prior to PHP 8.0.0, false was returned in this case.
Still, the timestamp can be retrieved as string by using
DateTimeInterface::format() with the U format.
