范例

Example #1 DateTime::setTime() example

面向对象风格

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

$date->setTime(14, 55);
echo $date->format('Y-m-d H:i:s') . "\n";

$date->setTime(14, 55, 24);
echo $date->format('Y-m-d H:i:s') . "\n";
?>

过程化风格

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

date_time_set($date, 14, 55);
echo date_format($date, 'Y-m-d H:i:s') . "\n";

date_time_set($date, 14, 55, 24);
echo date_format($date, '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

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

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

$date->setTime(14, 55, 24);
echo $date->format('Y-m-d H:i:s') . "\n";

$date->setTime(14, 55, 65);
echo $date->format('Y-m-d H:i:s') . "\n";

$date->setTime(14, 65, 24);
echo $date->format('Y-m-d H:i:s') . "\n";

$date->setTime(25, 55, 24);
echo $date->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
2001-01-02 01:55:24
