... year should be taken automatically ...
i was trying like this

but its not working as its taking current year every time.
Solução
Here is an example using the wonderful strtotime function of php.
<?php
$day = 1;
$month = 1;
$year = 2011;
$date = mktime(12, 0, 0, $month, $day, $year);
$targetMonth = 3;
$difference = $month - $targetMonth;
if($difference < 0) {
$difference += 12;
}
$sameDateInMarch = strtotime("- " . $difference . " months", $date);
echo "Entered date: " . date("d M Y", $date) . "<br />";
echo "Last 31 march: " . date("t M Y", $sameDateInMarch);
// the parameter 't' displays the last day of the month
?>

Something like this:
function getLast() {
$currentYear = date('Y');
// Check if it happened this year, AND it's not in the future.
$today = new DateTime();
if (checkdate(3, 31, $currentYear) && $today->getTimestamp() > mktime(0, 0, 0, 3, 31, $currentYear)) {
return $currentYear;
}
while (--$currentYear) {
if (checkdate(3, 31, $currentYear)) {
return $currentYear;
}
}
return false;
}
var_dump(getLast());
It should return the year or false
.
if (date('m')>3) {
$year = date('Y').'-'.(date('Y')+1);
} else {
$year = (date('Y')-1).'-'.date('Y');
}
echo $year;
this is to get the current financial year for India
