How to find the dates between two specified date?
i have three fields in my table
seeker
name ....current_time.... login_date
second field i have created through timestamp phpmyadmin
type: timestamp
default: current_timestamp
when seeker get registered his current_time automatically inserted by timestamp
third field is login_date filed. when user logins then this field is updated
//login date
$login_date = date("Y-m-d");
echo "login date"."".$login_date;
$qry1 = "update seeker set login_date = '$login_date' where name='$uname'";
$res1=mysql_query($qry1,$con);
now current_date is like
"2012-04-10 21:58:01"
and login_date is like
"2012-05-02"
i want to find number of days between these two dates. i dont know how to subtract these dates because current_date includes time too.. or is there any other way to exclude time from current-date i-e it enters only date not time
