示例 #1 DateTimeImmutable::setTime() example
面向对象风格
<?php
$date = new DateTimeImmutable('2001-01-01');
$newDate = $date->setTime(14, 55);
echo $date->format('Y-m-d H:i:s') . "\n";
$newDate = $date->setTime(14, 55, 24);
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(14, 55, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";
$newDate = $date->setTime(14, 55, 65);
echo $newDate->format('Y-m-d H:i:s') . "\n";
$newDate = $date->setTime(14, 65, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";
$newDate = $date->setTime(25, 55, 24);
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 2001-01-02 01:55:24
