Examples
Example #1 DateTime::__construct() example
Object oriented style
<?php try { $date = new DateTime('2000-01-01'); } catch (Exception $e) { echo $e->getMessage(); exit(1); } echo $date->format('Y-m-d'); ?>
Procedural style
<?php $date = date_create('2000-01-01'); if (!$date) { $e = date_get_last_errors(); foreach ($e['errors'] as $error) { echo "$error\n"; } exit(1); } echo date_format($date, 'Y-m-d'); ?>
The above examples will output:
2000-01-01
Example #2 Intricacies of DateTime::__construct()
<?php // Specified date/time in your computer's time zone. $date = new DateTime('2000-01-01'); echo $date->format('Y-m-d H:i:sP') . "\n"; // Specified date/time in the specified time zone. $date = new DateTime('2000-01-01', new DateTimeZone('Pacific/Nauru')); echo $date->format('Y-m-d H:i:sP') . "\n"; // Current date/time in your computer's time zone. $date = new DateTime(); echo $date->format('Y-m-d H:i:sP') . "\n"; // Current date/time in the specified time zone. $date = new DateTime(null, new DateTimeZone('Pacific/Nauru')); echo $date->format('Y-m-d H:i:sP') . "\n"; // Using a UNIX timestamp. Notice the result is in the UTC time zone. $date = new DateTime('@946684800'); echo $date->format('Y-m-d H:i:sP') . "\n"; // Non-existent values roll over. $date = new DateTime('2000-02-30'); echo $date->format('Y-m-d H:i:sP') . "\n"; ?>
The above example will output something similar to:
2000-01-01 00:00:00-05:00 2000-01-01 00:00:00+12:00 2010-04-24 10:24:16-04:00 2010-04-25 02:24:16+12:00 2000-01-01 00:00:00+00:00 2000-03-01 00:00:00-05:00
