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
