date_diff()

example:

$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);
echo $interval->format('%R%a days');

$date1 = date("Y/m/d");
$comp_date = "2010/12/1";

if($date1 <= $comp_date)//-------- if for date is less than limit

{

}

else if($date1 > $comp_date)//---------ElseIf for date is greator than limit                      

{


}//----End else if($date1 > $comp_date)

}//--------- End Main if

You can try this method too...
