this is actually pretty easy to do. it does require some code, but it is not hard to understand. simply use the date you recieve from your database info as the second param in your date function. Since you want it in "l, F, Y" format you have to do this:
get day, month, year seperate:
$dday = substr($date1, 8, 2);
$dmonth = substr($date1, 5, 2);
$dyear = substr($date1, 0, 4);
now you need to convert that into a timestamp using mktime. since you dont know the time and just the date you need to leave the first 3 elements of mktime blank:
$date1 = mktime("","","",$dmonth,$dday,$dyear);
$date2 = date("l, F, Y", $date1);
that should set $date2 equal to what you want.
