Getting ages from birthdays

[Anon]

I want to be able to get someone's age from a birthday, the dates are stored in a database in the form YYYY-MM-DD. I have tried to use timestamps but it won't work for anyone born before 1970.

Yeah, timestamps are in Unix Epoch time and epoch is the number of seconds elapsed since December 31, 1969.

What you could do is:

//$date is the date from the DB in the form YYYY-MM-DD

$date = explode("-", $date);
//now $date[0]=YYYY, $date[1]=MM, $date[2]=DD

$yyyy = date("y");
$mm = date("m");
$dd = date("d");

if( $date[0] < $yyyy ){
$diff[y] = $date[0]-$yyyy;
}
elseif( $date[0] = $yyyy ){
$diff[y] = 0;
}
else{ //$yyyy is smaller than user inputted year
print "Hey! You cant be born in $date[0]!";
}

//then repeat for mm and dd.

Hope this helps!
