Description:
------------
Try first $month = 11,$year = 2007 then $month =12, $year = 2007
Function returns correct value which seems not to be passed correctly.

Reproduce code:
---------------
function fixdate(&$month, &$year) {
	if ($month < 1) {
		$month = 12;
		$year--;
	} elseif ($month > 12) {
		$month = 1;
		$year++;
	}
}

fixdate($nextmonth = ($month + 1), $nextyear = ($year + 0));



Expected result:
----------------
12 / 2007 or 01 / 2008 

Actual result:
--------------
you will get 13 / 2007 instead.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Sorry i don't understand what you mean. I use the pass-by-reference function with global variable.

This works by example also when using references. So there is going something wrong with php.

$prevmonth = ($month - 1);
$prevyear = ($year + 0);
$nextmonth = ($month + 1);
$nextyear = ($year + 0);

fixdate($prevmonth, $prevyear);
fixdate($nextmonth, $nextyear);

Can you please explain why it works until latest PHP release but not in 5.2.3 ?!
