Solution 3:
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
Solution 4:
Shortest approach:
$lastYear = (int)date("Y") - 1;
