Code to output users age based on birthdate

[arkkhoax]

This is most likely very simple and easy to do but I can't figure out how to output the users age in vbulletin based on their registration birth date. There does not seem to be a variable built in for it. Any help would be appreciated.

Thanks.

I think all the code needs to do is subtract the birth date year from the current year to get the age. Could anyone help me?

Oh, after much hunting and pulling my hair out I figured out how to get the age of the user. Hope other people searching around find this of help.

The variable that holds the birthdate is $vbulletin->userinfo['birthday']

To then turn it into an age I used this function.

PHP Code:

function birthday ($birthday)
{
    list($month,$day,$year) = explode("-",$birthday);
    $year_diff  = date("Y") - $year;
    $month_diff = date("m") - $month;
    $day_diff   = date("d") - $day;
    if ($month_diff < 0) $year_diff--;
    elseif (($month_diff==0) && ($day_diff < 0)) $year_diff--;
    return $year_diff;
}

echo birthday($vbulletin->userinfo['birthday']); //prints age
