i m using date  in dd/mm/yyyy format... I am using two variable for dates $date1 and $date2.... suppose todays date is stored in $date1--16/01/2010  and $date2 is 18/02/2010... can we know the exact day differnce between two dates.???

i think there is more efficient method to use but, now i can say :

$Difference = date('m/d/Y', mktime(0, 0, 0, m1, d1, y1) - mktime(0, 0, 0, m2, d2, y2));
