PHP Date Format Yyyy-Mm-Dd Minus or Add One Week from Now

PHP - Add one week to a user defined date

You can try this

$start_date = "2015/03/02";  
$date = strtotime($start_date);
$date = strtotime("+7 day", $date);
echo date('Y/m/d', $date);

PHP subtract 1 month from date formatted with date ('m-Y')

 <?php 
  echo $newdate = date("m-Y", strtotime("-1 months"));

output

07-2016

php - add + 7 days to date format mm dd, YYYY

$date = "Mar 03, 2011";
$date = strtotime($date);
$date = strtotime("+7 day", $date);
echo date('M d, Y', $date);

subtract 2 days from a date which is in m-d-Y H:i:s format in PHP

$currentdate= date('m-d-Y H:i:s');
echo $currentdate; //gives 06-22-2019 14:58:55

$date = date('m-d-Y H:i:s ', strtotime('-2 days', strtotime(date('Y-m-d H:i:s'))));
echo $date;  //gives 06-20-2019 14:58:55

PHP DateTime::modify adding and subtracting months

Why it's not a bug:

The current behavior is correct. The following happens internally:

1. +1 month increases the month number (originally 1) by one. This makes the date 2010-02-31.

2. The second month (February) only has 28 days in 2010, so PHP auto-corrects this by just continuing to count days from February 1st. You then end up at March 3rd.

How to get what you want:

To get what you want is by: manually checking the next month. Then add the number of days next month has.

I hope you can yourself code this. I am just giving what-to-do.

PHP 5.3 way:

To obtain the correct behavior, you can use one of the PHP 5.3's new functionality that introduces the relative time stanza first day of. This stanza can be used in combination with next month, fifth month or +8 months to go to the first day of the specified month. Instead of +1 month from what you're doing, you can use this code to get the first day of next month like this:

<?php
$d = new DateTime( '2010-01-31' );
$d->modify( 'first day of next month' );
echo $d->format( 'F' ), "\n";
?>

This script will correctly output February. The following things happen when PHP processes this first day of next month stanza:

1. next month increases the month number (originally 1) by one. This makes the date 2010-02-31.

2. first day of sets the day number to 1, resulting in the date 2010-02-01.

Date minus 1 year?

You can use strtotime:

$date = strtotime('2010-01-01 -1 year');

The strtotime function returns a unix timestamp, to get a formatted string you can use date:

echo date('Y-m-d', $date); // echoes '2009-01-01'

php get oldest record and add 1 week

You can use the Datetime object to add a week easily

http://php.net/manual/en/book.datetime.php

$date = new DateTime('2013-03-20 09:42:41');
$date->modify('+1 week');

format date and add or subtract number of days in date coming from mysql using php

As long as $result['startDate'] is a date type column, and you're on a version of php greater than 5.0.2, you're looking for:

 $startDate = $result['startDate'];
 $date=date('Y-m-d',strtotime($startDate. ' +1 day'));
 echo $date;

Adding one day to a date

<?php
$stop_date = '2009-09-30 20:24:00';
echo 'date before day adding: ' . $stop_date; 
$stop_date = date('Y-m-d H:i:s', strtotime($stop_date . ' +1 day'));
echo 'date after adding 1 day: ' . $stop_date;
?>

For PHP 5.2.0+, you may also do as follows:

$stop_date = new DateTime('2009-09-30 20:24:00');
echo 'date before day adding: ' . $stop_date->format('Y-m-d H:i:s'); 
$stop_date->modify('+1 day');
echo 'date after adding 1 day: ' . $stop_date->format('Y-m-d H:i:s');
