范例

示例 #1 DateTimeImmutable::setTimestamp() example

面向对象风格

<?php
$date = new DateTimeImmutable();
echo $date->format('U = Y-m-d H:i:s') . "\n";

$newDate = $date->setTimestamp(1171502725);
echo $newDate->format('U = Y-m-d H:i:s') . "\n";
?>

以上例程的输出类似于：

1272508903 = 2010-04-28 22:41:43
1171502725 = 2007-02-14 20:25:25
