Examples

Example #1 DateTime::setTimestamp example

Object oriented style

<?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";
?>

Procedural style

<?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";
?>

The above examples will output something similar to:

1272508903 = 2010-04-28 22:41:43
1171502725 = 2007-02-14 20:25:25

Notes

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";
?>

The above example will output something similar to:

1171502725 = 2007-02-14 20:25:25
