范例

示例 #1 DateTimeImmutable::setTime() example

面向对象风格

<?php
$date 
= new DateTimeImmutable('2001-01-01');

$newDate $date->setTime(1455);
echo 
$date->format('Y-m-d H:i:s') . "\n";

$newDate $date->setTime(145524);
echo 
$date->format('Y-m-d H:i:s') . "\n";
?>

以上例程的输出类似于:

2001-01-01 14:55:00
2001-01-01 14:55:24

示例 #2 Values exceeding ranges are added to their parent values

<?php
$date 
= new DateTimeImmutable('2001-01-01');

$newDate $date->setTime(145524);
echo 
$newDate->format('Y-m-d H:i:s') . "\n";

$newDate $date->setTime(145565);
echo 
$newDate->format('Y-m-d H:i:s') . "\n";

$newDate $date->setTime(146524);
echo 
$newDate->format('Y-m-d H:i:s') . "\n";

$newDate $date->setTime(255524);
echo 
$newDate->format('Y-m-d H:i:s') . "\n";
?>

以上例程会输出:

2001-01-01 14:55:24
2001-01-01 14:56:05
2001-01-01 15:05:24
