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

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

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
