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

Question

I\'m trying to subtract 1 month from a date.

$today = date(\'m-Y\');

This gives: 08-2016

How can I subtract a month to get 07

Answer 1

Try this,

$effectiveDate = date('2018-01'); <br> 
echo 'Date'.$effectiveDate;<br>
$effectiveDate = date('m-y', strtotime($effectiveDate.'+-1 months'));<br>
echo 'Date'.$effectiveDate;

Answer 2

$lastMonth = date('Y-m', strtotime('-1 MONTH'));

Answer 3

$currentMonth = date('m', time());
$currentDay = date('d',time());
$currentYear = date('Y',time());
$lastMonth = $currentMonth -1;
$one_month_ago=mkdate(0,0,0,$one_month_ago,$currentDay,$currentYear);

This could be rewritten more elegantly, but it works for me

Answer 4

if(date("d") > 28){
    $date = date("Y-m", strtotime("-".$loop." months -2 Day"));
} else {
    $date = date("Y-m", strtotime("-".$loop." months"));
}

Answer 5

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

output

07-2016

Answer 6

Depending on your PHP version you can use DateTime object (introduced in PHP 5.2 if I remember correctly):

<?php
$today = new DateTime(); // This will create a DateTime object with the current date
$today->modify('-1 month');

You can pass another date to the constructor, it does not have to be the current date. More information: http://php.net/manual/en/datetime.modify.php
