Description

Object oriented style

public DateTime::__construct ([ string $datetime = "now" [, DateTimeZone $timezone = NULL ]] )

Parameters

datetime

A date/time string. Valid formats are explained in Date and Time Formats.

Enter "now" here to obtain the current time when using the $timezone parameter.

timezone

A DateTimeZone object representing the timezone of $datetime.

If $timezone is omitted, the current timezone will be used.

Note:

The $timezone parameter and the current timezone are ignored when the$datetime parameter either is a UNIX timestamp (e.g. @946684800) or specifies a timezone (e.g. 2010-01-28T15:00:00+02:00).

Errors/Exceptions

Emits Exception in case of an error.

Changelog

7.1	From now on microseconds are filled with actual value. Not with '00000'.
5.3.0	If datetime contains an invaliddate/time format, then an exception is now thrown. Previously an error was emitted.

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:

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
