$date_from1 = new DateTime('1-9-2016');
$thisdate=$date_from1->add(new DateInterval('P1D'));
when I print_r($thisdate);
I am getting the output
DateTime Object ( [date] => 2016-09-02 00:00:00 [timezone_type] => 3 [timezone] => Australia/Sydney )
Expected Output:-
2016-09-02
You need to mention the date format.
Refer to the manual: DateTime::format Example
echo $thisdate->format('Y-m-d H:i:s');
Based on date-time format manual:- http://php.net/manual/en/datetime.format.php
<?php
$date_from1 = new DateTime('1-9-2016');
$thisdate=$date_from1->add(new DateInterval('P1D'));
//echo "<pre/>";print_r($thisdate);
echo $thisdate->format('Y-m-d');
Output:-
https://eval.in/634751
check this
$date_from1 = date("d/m/Y", strtotime("1-9-2016"));

I use the native PHP DateTime class for adding days to dates. But when dealing with negative dates, I encountered a strange bug. Depending on the millennium added or a day or two. Example:
$date_one = date_create("-1000-12-27");
date_modify($date_one, '+1 day');
//Return DateTime Object ( [date] => -1000-12-29 00:00:00 )
$date_two = date_create("-2000-12-27");
date_modify($date_two, '+1 day');
//Return DateTime Object ( [date] => -2000-12-28 00:00:00 )
$date_three = date_create("-3000-12-27");
date_modify($date_three, '+1 day');
//Return DateTime Object ( [date] => -3000-12-29 00:00:00 )
That is, depending on the parity of the millennium issue, or December 28 or December 29. Why is this happening? What is the problem?
When creating event I need to set event start and event end in datetime format (0000-00-00 00:00:00)
Then I have option to set weekly repeating of that event until specific date (0000-00-00)
But I can't insert repeating events properly in database. Here is what I have:
$startDateTime = '2015-04-30 10:30:00';
$endDateTime = '2015-04-30 11:30:00';
$repeatEndDate = '2015-06-01';
$timestamp = strtotime($startDateTime);
$day_of_week = date('l', $timestamp);
$step = 1;
$unit = 'W';
$repeatStart = new DateTime($startDateTime);
$repeatEnd = new DateTime($repeatEndDate);
$repeatStart->modify($day_of_week);
$interval = new DateInterval("P{$step}{$unit}");
$period = new DatePeriod($repeatStart, $interval, $repeatEnd);
foreach ($period as $key => $date ) {
$repeatQuery = 'INSERT INTO event(start,end,status,repeats) VALUES ("'.$startDateTime.'","'.$endDateTime.'","'.$status.'","'.$repeatEndDate.'")';
$repeatResult = mysqli_query($db, $repeatQuery) or die (mysqli_error($db));
}
When I do print_r($date); it looks like this, no actual time just 00:00:00
DateTime Object
(
[date] => 2015-04-30 00:00:00
[timezone_type] => 3
[timezone] => Europe/Berlin
)
I know that I can't insert values like that but I don't know how to get correct values from objects.
So in this example I need to insert events that begin in 10:30:00 and end in 11:30:00(events always end same day) every Thursday starting at 2015-04-30 and ending at 2015-06-01. How can this be achieved?
Thank you
The problem is you're calling DateTime::modify with a day name (currently 'Thursday'). This value is calculated from the $startDateTime variable, and then used to modify that variable, so the only effect it has, is resetting the Time portion of that DateTime instance back to 0:00:00.
The following gives me the results I would expect:
(I've commented out the parts you need to remove from yours, to make it easier to see the difference)
date_default_timezone_set('Etc/UTC');
$startDateTime = '2015-04-30 10:30:00';
$endDateTime = '2015-04-30 11:30:00';
$repeatEndDate = '2015-06-01';
#$timestamp = strtotime($startDateTime);
#$day_of_week = date('l', $timestamp);
$step = 1;
$unit = 'W';
$repeatStart = new DateTime($startDateTime);
$repeatEnd = new DateTime($repeatEndDate);
#$repeatStart->modify($day_of_week);
$interval = new DateInterval("P{$step}{$unit}");
$period = new DatePeriod($repeatStart, $interval, $repeatEnd);
foreach ($period as $key => $date ) {
echo($date->format('Y-m-d H:i:s')) . PHP_EOL;
}
The result from running the above is:
2015-04-30 10:30:00
2015-05-07 10:30:00
2015-05-14 10:30:00
2015-05-21 10:30:00
2015-05-28 10:30:00
When you modify your $repeatStart using the modify() method you are using the l format character which, according to the docs, returns
A full textual representation of the day of the week
by changing the $day_of_week format string to
$day_of_week = date('Y-m-d H:i:s', $timestamp);
I get the following output
DateTime Object
(
[date] => 2015-04-30 10:30:00
[timezone_type] => 3
[timezone] => Europe/London
)
DateTime Object
(
[date] => 2015-05-07 10:30:00
[timezone_type] => 3
[timezone] => Europe/London
)
DateTime Object
(
[date] => 2015-05-14 10:30:00
[timezone_type] => 3
[timezone] => Europe/London
)
DateTime Object
(
[date] => 2015-05-21 10:30:00
[timezone_type] => 3
[timezone] => Europe/London
)
DateTime Object
(
[date] => 2015-05-28 10:30:00
[timezone_type] => 3
[timezone] => Europe/London
)
Although, the modification is not actually necessary and the following code should achieve what you are looking for.
<?php
$startDateTime = '2015-04-30 10:30:00';
$endDateTime = '2015-04-30 11:30:00';
$repeatEndDate = '2015-06-01';
$step = 1;
$unit = 'W';
$repeatStart = new DateTime($startDateTime);
$repeatEnd = new DateTime($repeatEndDate);
$interval = new DateInterval("P{$step}{$unit}");
$period = new DatePeriod($repeatStart, $interval, $repeatEnd);
foreach ($period as $key => $date ) {
$repeatQuery = 'INSERT INTO event(start,end,status,repeats) VALUES ("'.$startDateTime.'","'.$endDateTime.'","'.$status.'","'.$repeatEndDate.'")';
$repeatResult = mysqli_query($db, $repeatQuery) or die (mysqli_error($db));
print_r($date);
}
I have a timestring comming from an XML File
1408226400
Now i want to convert this string into an DateTime object, but i'm getting the wrong result.
//This is an example for this Question, but with the real datestring
//My real code looks like this: $dbTurn->setStartDate(new \DateTime("#".$turn['cruiseStartDateString']));
$test = date("d-m-Y H:i", 1408226400);
$dateTime = new DateTime($test);
print_r($dateTime);
# result is DateTime Object ( [date] => 2014-08-16 18:00:00 [timezone_type] => 3 [timezone] => America/New_York )
But that is not the date i expected, because the result i should because is this:
2014-08-17 10:04:00
Also, taken from the real code i mentioned in the comment within the code, this snippet:
$dbTurn->setStartDate(new \DateTime($turn['cruiseStartDateString']));
Throws this error if i don't suppress the error message:
message => (string) DateTime::__construct(): Failed to parse time string (1408226400) at position 7 (4): Unexpected character
Is something wrong with the datestring or am i doing something wrong?
You don't need to create a formatted datestring using date() before passing to a DateTime object constructor:
$timestamp = 1408226400;
$dateTime = new DateTime('#' . $timestamp);
print_r($dateTime);
though you may also need to pass a timezone to the DateTime constructor as well
you can try this
date_default_timezone_set('Europe/Berlin');
$test = date("Y-m-d h:i:s", 1408226400);
$dateTime = new DateTime($test);
print_r($dateTime);
OUTPUT :
DateTime Object
(
[date] => 2014-08-17 12:00:00
[timezone_type] => 3
[timezone] => Europe/Berlin
)
I am retrieving a date in format of 2013-09-15 08:45:00 from the database, which is set in UTC and I need to change it to another dynamic timezone (based on user)
So far I've got
$datetime = $row->field_data_field_performance_times_field_performance_times_v;
$eventDate = DateTime::createFromFormat('Y-m-d H:i:s', $datetime, new DateTimeZone($user->timezone));
$performance_time = date_format($eventDate, 'l, j F, Y, H:i');
But it doesn't change the timezone. Any ideas what's wrong? It should be +2 hours in my case.
Your input datetime is in UTC, not user's timezone. So first you must create datetime object in UTC, and then set/change timezone to user's :
$dt = new DateTime('2013-09-15 08:45:00', new DateTimeZone('UTC'));
print_r($dt);
/*
DateTime Object
(
[date] => 2013-09-15 08:45:00
[timezone_type] => 3
[timezone] => UTC
)
*/
Now you have datetime in UTC timezone. If you wish to change timezone, just call ->setTimezone() on DateTime object :
$dt->setTimezone(new DateTimeZone('Europe/Berlin'));
print_r($dt);
/*
DateTime Object
(
[date] => 2013-09-15 10:45:00
[timezone_type] => 3
[timezone] => Europe/Berlin
)
*/
p.s. because input 2013-09-15 08:45:00 is in standard datetime format, you don't need to use DateTime::createFromFormat.
After more than an hour struggling and trying I'd like to ask it here.
Trying to make something with weeks etc. in php I got from you site this:
Get all Work Days in a Week for a given date
Nice and will work for me fine.
But ... I can't get, trying and trying, the data out of this part: [date] => 2013-08-12 00:00:00
Array
(
[0] => DateTime Object
(
[date] => 2013-08-12 00:00:00
[timezone_type] => 3
[timezone] => Europe/Amsterdam
)
How to get that date out of the array ?
Please help me out, thanks in advance for the help !
Use DateTime::format()
$dateTime = new DateTime('2013-08-12 00:00:00');
echo $datetime->format('Y-m-d'); // produces 2013-08-12
$firstMondayThisWeek= new DateTime('2013-08-12');
$firstMondayThisWeek->modify('tomorrow');
$firstMondayThisWeek->modify('last Monday');
$nextFiveWeekDays = new DatePeriod(
$firstMondayThisWeek,
DateInterval::createFromDateString('+1 weekdays'),
4
);
$dateTimes = iterator_to_array($nextFiveWeekDays);
foreach ($dateTimes as $dateTime) {
echo $dateTime->format('Y-m-d H:i:s');
}
