Example #1 DateTime::setTimestamp() example
面向对象风格
<?php
$date = new DateTime();
echo $date->format('U = Y-m-d H:i:s') . "\n";
$date->setTimestamp(1171502725);
echo $date->format('U = Y-m-d H:i:s') . "\n";
?>
过程化风格
<?php
$date = date_create();
echo date_format($date, 'U = Y-m-d H:i:s') . "\n";
date_timestamp_set($date, 1171502725);
echo date_format($date, 'U = Y-m-d H:i:s') . "\n";
?>
以上例程的输出类似于:
1272508903 = 2010-04-28 22:41:43 1171502725 = 2007-02-14 20:25:25
Using the Unix timestamp format to construct a new DateTime object is an alternative when using PHP 5.2, as shown in the example below.
Example #2 DateTime::setTimestamp() alternative in PHP 5.2
<?php
$ts = 1171502725;
$date = new DateTime("@$ts");
echo $date->format('U = Y-m-d H:i:s') . "\n";
?>
以上例程的输出类似于:
1171502725 = 2007-02-14 20:25:25
