示例 #1 DateTime::__unserialize() example

<?php

class CustomDateTimeImmutable extends DateTimeImmutable
{
    #[\Override]
    public function __unserialize(array $data): void
    {
        echo "Time to `{$data['to']}`:\n\n";

        parent::__construct($data['date'], new DateTimeZone($data['timezone']));
    }
}

$serializedData = 'O:23:"CustomDateTimeImmutable":4:{s:4:"date";s:25:"2025-03-27T00:00:00+00:00";s:9:"timestamp";i:1743033600;s:8:"timezone";s:3:"UTC";s:2:"to";s:21:"Drink a cup of coffee";}';

var_dump(unserialize($serializedData));

以上示例会输出：

Time to `Drink a cup of coffee`:

object(CustomDateTimeImmutable)#1 (3) {
  ["date"]=>
  string(26) "2025-03-27 00:00:00.000000"
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "+00:00"
}
