A nice way to calc age seeing that mktime only goes back until 1970 is to use the date function like
this...
//Find the difference in year, month, and day
$yeardiff = date("Y") - $dobyear;
$monthdiff = date("m") - $dobmonth;
$daydiff = date("j") - $dobday;
/*
* if month or day is negative we have yet to reach it so
* we need to subtract a year seeing we haven't
* reached our birthday yet, else yeardiff is correct
*/
if($monthdiff < 0 || $daydiff < 0){
$age = $yeardiff - 1;
}else{
$age = $yeardiff;
}
echo $age;
