Getting a users age from their date of birth

[TeddyKiller]

How can I do this?

The variable for the dob is $dob.

 

Thanks

I tried this function (see below), but this always returns 40.

I figured it's because the DOB in the database isn't a timestamp.. so how could I change this so that it works.

 

function getAge($iTimestamp)
{
    $iDiffYear  = date('Y') - date('Y', $iTimestamp);
    $iDiffMonth = date('n') - date('n', $iTimestamp);
    $iDiffDay   = date('j') - date('j', $iTimestamp);
    
    // If birthday has not happen yet for this year, subtract 1.
    if ($iDiffMonth < 0 || ($iDiffMonth == 0 && $iDiffDay < 0)) {
        $iDiffYear--;
    }
        
    return $iDiffYear;
}
