get last day of the next month in php? - php

I have a php code as shown below in which I am trying to retrieve the last day of next month.
<?php
date_default_timezone_set('America/Toronto');
echo date('l jS \of F Y h:i:s A');
$next_month_last_day = date('t', strtotime('next month')); // last day of the next month
print_r("\n");
print_r($next_month_last_day); // Line A
?>
Problem Statement:
I am wondering what mistake I have done in the php code above because the code at Line A prints 31. It should be printing 30 because the last
day of next month (April) is 30.

Just use
date('d', strtotime('last day of +1 month'));

You can use last day of next month
$date = new \DateTime('last day of next month');
echo $date->format('Y-m-d');

Another way to go about it is to get the first day of the next month, then use t to format it to the number of days of that month.
echo date("t", strtotime("first day of next month")); // 2021-04-30 10:27:35

I had to manually overwrite today's day so DateTime wouldn't skip a month. But it doesn't matter since you only want to know what the next month is.
$dateTime = new DateTime('now', new DateTimeZone("America/Toronto"));
$dateTime->setDate($dateTime->format('Y'), $dateTime->format('m'), 01);
$nextMonth = $dateTime->modify('+1 month');
echo cal_days_in_month(CAL_GREGORIAN, $nextMonth->format('m'), $nextMonth->format('Y'));

Try This
$lastDay = date('t',strtotime('next month'));
print_r($lastDay);

Get the last day of the last month and the first day of next month in PHP

If i have for example :
'2020-01-01'
I want to have two dates :
-The last day of the prévious month :
'2019-12-31'
-The first day of next month :
'2020-02-01'
I tried to use something like echo date("Y-n-31", strtotime('2020-01-01')); but i don't know.
Thank you.
Use below code:
<?php
$month_end = new DateTime("last day of last month");
$month_ini = new DateTime("first day of next month");
echo $month_end->format('Y-m-d'); // will print, Last day of last month
echo $month_ini->format('Y-m-d'); // will print First day of next month
?>
With Datetime object with user defined date (Custom date)
# with datetime object
$d1 = new DateTime('2019-12-01');
$d1 -> modify('last day of last month');
echo $d1 -> format('d.m.Y'), "\n";
$d2 = new DateTime('2019-12-01');
$d2 -> modify('first day of next month');
echo $d2 -> format('d.m.Y'), "\n";
Output:
30.11.2019
01.01.2020
Try this, Use strtotime() for add month or minus month
$date='2020-01-01';
echo date("Y-m-t", strtotime('-1 month'.$date)); //2019-12-31
echo date("Y-m-01", strtotime('+1 month'.$date)); //2020-02-01
strtotime()
this php function convert english textual date-time discription into UNIX timestamp
the first step converts textual date-time into a timestamp
now you have timestamp then use the date() function
-The last day of the prévious month :
echo date("Y-m-d", strtotime("Last day of last month"));
-The first day of next month :
echo date("Y-m-d", strtotime("First day of next month"));
You can use DateTime's method modify() to achieve relative dates:
<?php
$dateOld = new \DateTimeImmutable('2020-01-01');
echo $dateOld->modify("last day of last month")->format('Y-m-d');
echo PHP_EOL;
echo $dateOld->modify("first day of next month")->format('Y-m-d');
Try it here: https://3v4l.org/qALa5
$date='2020-01-01';
echo date("Y-m-d", 'last day of previous month', strtotime($date)));
echo date("Y-m-d", 'first day of next month', strtotime($date)));

How to get the next month in PHP

I need to get the next month with php. Everywhere is written these example
date('Y-m-t', strtotime('+1 month'));
The output of the above code is '2017-03-31'. I need to get February, not March.
If you want to get the next irrespective of the current date in the current month. below code may help you
echo date('M',strtotime('first day of +1 month'));
// e.g. "Jan"
echo date('m',strtotime('first day of +1 month'));
// e.g. "1"
echo date('F',strtotime('first day of +1 month'));
// e.g. "January"
This will give you Next month.
You can find more formatting masks in date() function documentation
Use Like This
// One month from today
$date = date('Y-m-d', strtotime('+1 month'));
// One month from a specific date
$date = date('Y-m-d', strtotime('+1 month', strtotime('2015-01-01')));
To get next month using php use string to time function as below:
$nxtm = strtotime("next month");
echo date("M", $nxtm);
date("m", strtotime("2021-08-16 +1 Month"));
You can use the code below to get the next months first day.
$date = (new \DateTime('first day of next month'))->format('Y-m-d');
This is safer than 'next month' or '+1 month' because you may skip some months then.
If you want to have the next month with the same day as this month, or the last day of the next month if it otherwise would switch month you can use this function
function nextMonth()
{
$nextMonthNumber = date('M', strtotime('first day of +1 month'));
$nextMonthDate = new DateTime();
$nextMonthDate->add(new DateInterval('P1M'));
while ($nextMonthDate->format('M') != $nextMonthNumber) {
$nextMonthDate->sub(new DateInterval('P1D'));
}
return $nextMonthDate;
}

Display next first Sunday without specifying month in PHP [duplicate]

I can get the Monday of this week with:
$monday = date_create()->modify('this Monday');
I would like to get with the same ease the 1st of this month. How can I achieve that?
Here is what I use.
First day of the month:
date('Y-m-01');
Last day of the month:
date('Y-m-t');
Requires PHP 5.3 to work ("first day of" is introduced in PHP 5.3). Otherwise the example above is the only way to do it:
<?php
// First day of this month
$d = new DateTime('first day of this month');
echo $d->format('jS, F Y');
// First day of a specific month
$d = new DateTime('2010-01-19');
$d->modify('first day of this month');
echo $d->format('jS, F Y');
// alternatively...
echo date_create('2010-01-19')
->modify('first day of this month')
->format('jS, F Y');
In PHP 5.4+ you can do this:
<?php
// First day of this month
echo (new DateTime('first day of this month'))->format('jS, F Y');
echo (new DateTime('2010-01-19'))
->modify('first day of this month')
->format('jS, F Y');
If you prefer a concise way to do this, and already have the year and month in numerical values, you can use date():
<?php
echo date('Y-m-01'); // first day of this month
echo "$year-$month-01"; // first day of a month chosen by you
This is everything you need:
$week_start = strtotime('last Sunday', time());
$week_end = strtotime('next Sunday', time());
$month_start = strtotime('first day of this month', time());
$month_end = strtotime('last day of this month', time());
$year_start = strtotime('first day of January', time());
$year_end = strtotime('last day of December', time());
echo date('D, M jS Y', $week_start).'<br/>';
echo date('D, M jS Y', $week_end).'<br/>';
echo date('D, M jS Y', $month_start).'<br/>';
echo date('D, M jS Y', $month_end).'<br/>';
echo date('D, M jS Y', $year_start).'<br/>';
echo date('D, M jS Y', $year_end).'<br/>';
Currently I'm using this solution:
$firstDay = new \DateTime('first day of this month');
$lastDay = new \DateTime('last day of this month');
The only issue I came upon is that strange time is being set. I needed correct range for our search interface and I ended up with this:
$firstDay = new \DateTime('first day of this month 00:00:00');
$lastDay = new \DateTime('first day of next month 00:00:00');
I use a crazy way to do this is using this command
$firstDay=date('Y-m-d',strtotime("first day of this month"));
$lastDay=date('Y-m-d',strtotime("last day of this month"));
Thats all
In php 5.2 you can use:
<? $d = date_create();
print date_create($d->format('Y-m-1'))->format('Y-m-d') ?>
Ugly, (and doesn't use your method call above) but works:
echo 'First day of the month: ' . date('m/d/y h:i a',(strtotime('this month',strtotime(date('m/01/y')))));
You can do it like this:
$firstday = date_create()->modify('first day January 2010');
using date method, we should be able to get the result.
ie; date('N/D/l', mktime(0, 0, 0, month, day, year));
For Example
echo date('N', mktime(0, 0, 0, 7, 1, 2017)); // will return 6
echo date('D', mktime(0, 0, 0, 7, 1, 2017)); // will return Sat
echo date('l', mktime(0, 0, 0, 7, 1, 2017)); // will return Saturday
I use this with a daily cron job to check if I should send an email on the first day of any given month to my affiliates. It's a few more lines than the other answers but solid as a rock.
//is this the first day of the month?
$date = date('Y-m-d');
$pieces = explode("-", $date);
$day = $pieces[2];
//if it's not the first day then stop
if($day != "01") {
echo "error - it's not the first of the month today";
exit;
}
Timestamp for start of this month and very last second of current month.
You can add 00:00:00 or just reference "today"
Alternative:
$startOfThisMonth = strtotime("first day of this month",strtotime("today"));
OR
$startOfThisMonth = strtotime("first day of this month 00:00:00");
$endOfThisMonth = strtotime("first day of next month",$startOfThisMonth)-1;
I am providing this answer as an alternative one liner if the DateTime object is not preferred
Basically, I get the current day number, reduce it by one then take that number of days from itself ("today" which automatically resets the clock to 00:00:00 too) and you get the start of the month.
$startOfMonth = strtotime("today - ".(date("j")-1)." days");
If you're using composer, you can install carbon:
composer require nesbot/carbon
This is then as simple as:
use Carbon/Carbon;
$startOfMonth = Carbon::now()->startOfMonth()->toDateTime();

Finding First day of week via php [duplicate]

Get first day of week in PHP?
Hi,
I want to find first and last date of current week and last week.
Similarly I want to find first and last date of current month and last month.
This has to be done in PHP. Please help.
strtotime is quite powerful with relative time formats:
strtotime('monday this week');
strtotime('sunday this week');
strtotime('monday last week');
strtotime('sunday last week');
(this only works with PHP 5.3+)
strtotime('first day of this month');
strtotime('last day of this month');
strtotime('first day of last month');
strtotime('last day of last month');
In order to get the first and last date of a month in PHP < 5.3, you can use a combination of mktime and date (date('t') gives the number of days of the month):
mktime(0,0,0,null, 1); // gives first day of current month
mktime(0,0,0,null, date('t')); // gives last day of current month
$lastMonth = strtotime('last month');
mktime(0,0,0,date('n', $lastMonth), 1); // gives first day of last month
mktime(0,0,0,date('n', $lastMonth), date('t', $lastMonth); // gives last day of last month
If you just want to get a string for presentation, then you don't need mktime:
date('Y-m-1'); // first day current month
date('Y-m-t'); // last day current month
date('Y-m-1', strtotime('last month')); // first day last month
date('Y-m-t', strtotime('last month')); // last day last month
Here's a function for the first and last day of the week:
function week_start_date($wk_num, $yr, $first = 1, $format = 'F d, Y')
{
$wk_ts = strtotime('+' . $wk_num . ' weeks', strtotime($yr . '0101'));
$mon_ts = strtotime('-' . date('w', $wk_ts) + $first . ' days', $wk_ts);
return date($format, $mon_ts);
}
$sStartDate = week_start_date($week_number, $year);
$sEndDate = date('F d, Y', strtotime('+6 days', strtotime($sStartDate)));
It can probably be adapted to do month as well, but I wanted to get my answer in! :)
