范例

Example #1 DateTime::setTime() example

面向对象风格

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

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

$date->setTime(145524);
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($date1455);
echo 
date_format($date'Y-m-d H:i:s') . "\n";

date_time_set($date145524);
echo 
date_format($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(145524);
echo 
$date->format('Y-m-d H:i:s') . "\n";

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

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

$date->setTime(255524);
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
