comparing two dates

[greedyisg00d]

I have 2 variables and I want to check if both variables belong to a same month and year regardless of the day for example:

$date1 = 09/10/2009;
$date2 = 10/11/2009;
//It will display an error like

echo "Both dates do not belong on the same month";

Any idea on how can this be done? Sample code is much appreciated.

Thanks

Something like this:

$date1 = strtotime("09/10/2009");
$date2 = strtotime("10/11/2009");
$date3 = strtotime("10/10/2009");
//It will display an error like

if (date('m-y',$date1) != date('m-y',$date2)) {
 	echo "Both dates do not belong on the same month";
 }else {
 	echo "Dates Match";
 }


if (date('m-y',$date3) != date('m-y',$date2)) {
 	echo "Both dates do not belong on the same month";
 } else {
 	echo "Dates Match";
 }
