[SOLVED] Subtract dates to get age

[SkyRanger]

I am trying to figure out how to get a visitors age from the date they submitted.

 

I tried a number of things which either a: didn't work or b: had so much code it confused the heck out of me and still didn't work.

 

I tried things like:

 

$bdate = March 31 1972

$age = date('F d Y') - $bdate 

 

Tried breaking them down into different parts, but that still didn't work, any help would be greatly apprectiated.

 

So what I am trying todo is say subtract bdate from todays date so for example it would say Age: 35

 

Or if the bday was May 24 1972 then the age would say Age: 34

 

Any help would be greatly appreciated.

Subtract year of birth from this year to get age

 

Then compare mmdd of date of birth with mmdd of current date.

 

If birth mmdd is greater, they haven't had their birthday yet this year so decrement age.

Awsome, thanks barand,figured it out.

 

           $birthyear = $rowpref['byear'];
   $birthday = $rowpref['bday'];
   $birthmonth = $rowpref['bmonth'];
   
$year_diff = date("Y") - $birthyear;
        $month_diff = date("m") - $birthmonth;
        $day_diff = date("d") - $birthday;
            if ($month_diff < 0)
               $year_diff--;
            elseif ($month_diff == 0 && $day_diff < 0)
               $year_diff--;
  
echo $year_diff;
