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("Yn-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 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)));
