PHP: Return all dates between two dates in an array [duplicate]
(26 answers)
Closed 7 years ago.
I have a form that the user should fill two dates.I want to display dates between those selected dates like
June 11
June 12
June 13
June 14
June 15
Jun 16
Jun 17
in my action.php
$dateTo = $r->getParameter("date_to", date('Y-m-d'));
$dateFrom = $r->getParameter("date_from", date('Y-m-d', strtotime('7 days ago', strtotime($dateTo))));
$dateRange = new DatePeriod(DateTime::createFromFormat('Y-m-d',$dateTo), new DateInterval('P1D'), DateTime::createFromFormat('Y-m-d',$dateFrom));
then in my templates, I tried
foreach $dateRange as $date {echo $date}
Whats the correct way to display those date?
var_dump outputs like
object(DatePeriod)[62]
public 'start' =>
object(DateTime)[21645]
public 'date' => string '2015-05-20 16:56:21' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'Asia/Manila' (length=11)
public 'current' => null
public 'end' =>
object(DateTime)[21656]
and I tried
<?php foreach($dateRange as $r):?>
<?php echo $r->format('Y-m-d') ?>
<?php endforeach ?>
But nothing displayed in my table
According to the PHP doc DatePeriod implements the Traversable interface. So you can use it like an array and loop with a foeeach over it:
/** #var DateTime[] $dateRange */
$dateRange = new DatePeriod(...);
foreach($dateRange as $date) {
$date->format(...);
}
What is not mentioned in the official PHP doc is that you get an "array" of DateTime objects.
You need to use format.
Like this:
echo $date->format("Ymd") . "<br>";

Convert one date format into another in PHP
(17 answers)
Closed 9 months ago.
I would like to get next day.
$nextSunday = date($saturdayList[$k], strtotime("+1 day"));
saturdayList array is
Array
(
[
0
] => 2022-11-05
[
1
] => 2022-11-12
[
2
] => 2022-11-19
[
3
] => 2022-11-26
)
When $k is 0
nextSunday return
2022-11-05
Please refer to the manual page for the date function here: https://www.php.net/manual/en/function.date.php.
You can see that the first param should be the format of the returned date, e.g. 'Y-m-d', not the date you want to add 1 day to.
The code should be something like
$nextSunday = date('Y-m-d', strtotime($saturdayList[$k] . " +1 day"));
The second parameter of strtotime takes a base timestamp. So pass in the timestamp of the date as the second parameter.
$nextSunday = date("Y-m-d", strtotime("+1 day", strtotime($saturdayList[$k])));

Convert day of the year to datetime in php
(2 answers)
Closed 2 years ago.
I'm trying to convert day of year into date.
So no problem i use DateTime::createFromFormat with z and Y.
DateTime::createFromFormat('z Y', '199 2020');
/*RESULT*/
object(DateTime)[3]
public 'date' => string '2020-07-19 12:45:24.000000' (length=26)
public 'timezone_type' => int 3
public 'timezone' => string 'Europe/Paris' (length=12)
But when i test the result i get the wrong day of year...
date('z Y', strtotime('2020-07-19'));
/*RESULT*/
'198 2020' (length=8)
So i trying this
DateTime::createFromFormat('z Y', date('z Y', strtotime('2020-07-19')));
/*RESULT*/
object(DateTime)[3]
public 'date' => string '2020-07-20 12:52:10.000000' (length=26)
public 'timezone_type' => int 3
public 'timezone' => string 'Europe/Paris' (length=12)
if i check day of year 199 of 2020 on this website: https://www.calendrier.best/numero-de-jour-2020.html
I get 2020-07-17
What i'm doing wrong ??
If you know the year, you can use something like this. Outputs:
string(10) "2020-07-17"
Code:
<?php
$dayOfYearNumber = 199;
$year = 2020;
// Add day of year number to the first day of the year, substracting 1 because Jan 1st will be the first day.
$date = (new DateTime("$year-1-1"))->add(new DateInterval('P' . $dayOfYearNumber - 1 . 'D'));
var_dump($date->format('Y-m-d')); // string(10) "2020-07-17"
PHP only detects some standards like you can see here https://www.php.net/manual/de/datetime.formats.date.php
In Your first example you defined your format but strtotime() has no such parameter
If you have these values as variable you could use mktime() instead https://www.php.net/manual/de/function.mktime
But I recommend to always give PHP a month e.x. January
The following code works if I manually type in every day for every single month in each hard coded array.
I then loop through the arrays for a match and if I find it, I return the first index and the last index value of that array. These are the pay period start and end dates later to be used with mysql select queries.
// MOUNTAIN DAYLIGHT SAVINGS TIME
date_default_timezone_set('MST7MDT');
// = PHP Default TimeZone
//print 'MOUNTAIN DAYLIGHT SAVINGS TIME';
//print '<p>';
// = MySQL CURRDATE() in MySQL DATETIME Format.
$php_current_date = date('Y-m-d');
// 2019 Pay Periods - MONTHLY
$parent_array = array(
1 => array('2019-01-01','2019-01-31'),

I have tried to implement the solution below but, I keep getting errors related to me not being able to compare date strings... It seems I have learned to find date strings in an array of arrays but they aren't really dates as far as php is concerned.
/**
* #param DateTime $date Date that is to be checked if it falls between $startDate and $endDate
* #param DateTime $startDate Date should be after this date to return true
* #param DateTime $endDate Date should be before this date to return true
* return bool
*/
function isDateBetweenDates(DateTime $date, DateTime $startDate, DateTime $endDate) {
return $date > $startDate && $date < $endDate;
}
$fromUser = new DateTime("2012-03-01");
$startDate = new DateTime("2012-02-01 00:00:00");
$endDate = new DateTime("2012-04-30 23:59:59");
echo isDateBetweenDates($fromUser, $startDate, $endDate);
Here's how I try to call it and get the error...
isDateBetweenDates($php_current_date, $current_pay_period_start, $current_pay_period_end);
I have wrote the following for you, that compares the two dates from your array. Hopefully it will help!
$php_current_date = date('Y-m-d');
$parent_array = array(
1 => array('2019-01-01','2019-01-31'),

i am trying to figure out how to get total Months in between two overlapping date Ranges.
e-g
Date Range from Date-A to Date-B overlapping the Date range of Date-X and Date-Y.
_ Start|Jan - Feb - March - April ------ Nov - Dec|End (DateRange A)
Start|Jan - Feb ---- Dec - Jan - Feb|End _
In two date ranges the Jan and Feb Months are colliding. Means Total of 2 Months are there.
So i want these two months in my array so i can apply different functions on it.
e-g i have these two dates
$dateRange1Start = "2015-07-01";
$dateRange1End = "2014-06-30";
=-=-=-=====-=-==
$dateRange2Start = "2012-02-01";
$dateRange2End = "2014-12-31";
There are total 6 Months in colliding between these two date ranges. i want to get these 6 Months.
I tried to search for help in google, but mostly i get less than or greater than signs. but specifically like this. I tried to implement my own logic but its not getting me anywhere, sadly to only more problems :(
i am trying to get results like this
$collidingDates = array("2014-07","2014-08","2014-09","2014-10","2014-11","2014-12");
Any help would be appreciated. :)
=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=--=-=
UPDATE:
Here is what i have done so far, yes getting some code from here and there. and tweaking it a bit up to fulfill my requirements.
//Getting all Months from First Date Range
$start = (new DateTime('2014-06-01'))->modify('first day of this month');
$end = (new DateTime('2015-05-06'))->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$firstPeriod = new DatePeriod($start, $interval, $end);
//Getting all Months from Second Date Range.
$start = (new DateTime('2012-02-01'))->modify('first day of this month');
$end = (new DateTime('2014-12-31'))->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$secondPeriod = new DatePeriod($start, $interval, $end);
$collidingDates = array();
foreach ($firstPeriod as $f_dt) {
foreach($secondPeriod as $s_dt){
if($f_dt->format("Y-m") === $s_dt->format("Y-m")){
array_push($collidingDates,$f_dt->format("Y-m"));
}
}
}
echo "<pre>";
print_r($collidingDates);
i got this output.
Array
(
[0] => 2014-06
[1] => 2014-07
[2] => 2014-08
[3] => 2014-09
[4] => 2014-10
[5] => 2014-11
[6] => 2014-12
)
But i think i am getting 1 extra month
2014-06, not sure how O_o??
This is a two step process. First you need to establish the narrowest date range from the start and end dates. Then list the months between those dates.
// An array of start and end dates. There are just 2 in this example but you
// could have as many as you like in the same "start, then end" format.
$ranges = [
[new DateTime('2014-07-01'), new DateTime('2015-06-30')],
[new DateTime('2012-02-01'), new DateTime('2014-12-31')]
];
// Reduce the ranges to one set of two dates, the latest of the start dates
// and the earliest of the end dates.
$range = array_reduce($ranges, function($carry, $item){
return $carry
? [max($carry[0], $item[0]), min($carry[1], $item[1])]
: $item;
});
var_dump($range);
/*

*/
// Shift both dates to the first of the month. Strictly speaking, we only

var_dump($range);

I think you are looking for this:
$start = (
new DateTime('2015-12-02'))
->modify('first day of this month');
$end = (new DateTime('2016-05-06'))->modify('first day of next month');
$interval = DateInterval::createFromDateString('1 month');
$period = new DatePeriod($start, $interval, $end);
foreach ($period as $dt) {
echo $dt->format("Y-m") . "<br>\n";
}
I looked at this answer already, and it's quite close to what I have.
Here is my PHP code:
$start = new DateTime('0:00 first day of previous month', new DateTimeZone('UTC'));
/*
if (isset($_GET['year']) && isset($_GET['month']) && checkdate($_GET['month'], 1, $_GET['year'])) {
$start = DateTime::createFromFormat('Y-m-d', $_GET['year'] . '-' . $_GET['month'] . '-1');
}*/
$middle = DateTime::createFromFormat('U', strtotime('first day of last month', $start->format('U')));
$middle->setTimezone(new DateTimeZone('UTC'));
$end = DateTime::createFromFormat('U', strtotime('first day of 2 months ago', $start->format('U')));
$end->setTimezone(new DateTimeZone('UTC'));
var_dump($start);
var_dump($middle);
var_dump($end);
Today is August 27th, so I would expect July 1, June 1, and May 1. Here's what the actual output is:
object(DateTime)[1]
public 'date' => string '2013-07-01 00:00:00' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'UTC' (length=3)
object(DateTime)[2]
public 'date' => string '2013-05-02 00:00:00' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'UTC' (length=3)
object(DateTime)[3]
public 'date' => string '2013-04-02 00:00:00' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'UTC' (length=3)
Why is it returning the second day of the months for me?
I've also tried it without the new DateTimeZone('GMT') as the second parameter of the constructor for the initial DateTime but it still gives me the same result, just with different times.
this part irrelevant - question was edited
Because of the timezone difference. $start is calculated in the 'Rainy River timezone', while $middle and $end are in UTC time.
The 'Rainy River timezone has a -06:00 hour offset from UTC (exactly the difference in hours between the first with the second and third results).
update 1 - solution
It seems the problem lies somewhere around strtotime. For some reason it yields a result with an offset of one day (further explanation needed). A simple solution, is to subtract one second from that date and it will produce the correct result.
$timezone = new DateTimeZone('UTC');
$start = new DateTime('0:00 first day of previous month', $timezone );
$middle = DateTime::createFromFormat('U', strtotime('first day of last month',($start ->format('U'))-1),$timezone);
echo $middle->format('Y-m-d')."\n";
Result:
2013-05-01
update 2 - reason for problem
Eventually I find out that the problem originates from the instantiation of the fisrt date object. Here is an illustration.
This will give a correct result:
$original = new DateTime('2013-05-01');
echo $original->format('Y-m-d')."\n";
$previous= DateTime::createFromFormat('U', strtotime('first day of last month',($original->format('U'))),new DateTimeZone('UTC'));
echo $previous->format('Y-m-d')."\n";
Result (OK):
2013-05-01
2013-04-01 <--- OK
However, this will not (only first line different, as in the original code):
$original = new DateTime('0:00 first day of previous month', new DateTimeZone('UTC'));
echo $original->format('Y-m-d')."\n";
$previous= DateTime::createFromFormat('U', strtotime('first day of last month',($original->format('U'))),new DateTimeZone('UTC'));
echo $previous->format('Y-m-d')."\n";
Result:
2013-07-01
2013-05-02 <--- BAD
After reading the answer here, I had a better idea:
$start = new DateTime('0:00 first day of previous month');
/*
if (isset($_GET['year']) && isset($_GET['month']) && checkdate($_GET['month'], 1, $_GET['year'])) {
$start = DateTime::createFromFormat('Y-m-d', $_GET['year'] . '-' . $_GET['month'] . '-1');
}*/
$middle = clone $start;
$middle->modify('first day of last month');
$end = clone $start;
$end->modify('first day of 2 months ago');
var_dump($start);
var_dump($middle);
var_dump($end);
Output:
object(DateTime)[1]
public 'date' => string '2013-07-01 00:00:00' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'America/Rainy_River' (length=19)
object(DateTime)[2]
public 'date' => string '2013-06-01 00:00:00' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'America/Rainy_River' (length=19)
object(DateTime)[3]
public 'date' => string '2013-05-01 00:00:00' (length=19)
public 'timezone_type' => int 3
public 'timezone' => string 'America/Rainy_River' (length=19)
Also, I realize that a DateTimeImmutable would be a better choice for the $start instance (so that I don't have to clone the other two), but I don't have access to PHP 5.5 yet.
