How to get previous year using PHP

Question

How am I able to get the value of the previous year using PHP. Are there any predefined functions for it?

Answer 1

There are many ways, you can either take away the amount of seconds in a year from time() like so:

$prevYear = date('Y', time() - 60*60*24*365 );

Or if you'd prefer, use the PHPs clever strtotime() function:

$prevYear = date('Y', strtotime('-1 year'));

Or even like others have said, if it's from todays year just do date('Y') -1
