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'); 
 
echo 'Date'.$effectiveDate;

$effectiveDate = date('m-y', strtotime($effectiveDate.'+-1 months'));

echo 'Date'.$effectiveDate;
