Formatere delvise ukendte datoer med DateTime() fra en database?

Lige hvad jeg ledte efter (og ikke ønskede at høre).

Her er en grundlæggende php-funktion for dem af jer, der er dovne som mig.

function formatDatabaseDate($date, $delimiter = '/')
{
    // this function works only on mysql date fields, 
    // and takes into account partial dates.
    if ($date != '' && $date != NULL)
    {
        $datePieces = explode('-', $date);
        if (count($datePieces) == 3 && 
            strlen($datePieces[0]) == 4 && 
            strlen($datePieces[1]) == 2 && 
            strlen($datePieces[2]) == 2)
        {
            $datestring = '';

            $months['01'] = 'Jan';
            $months['02'] = 'Feb';
            $months['03'] = 'Mar';
            $months['04'] = 'Apr';
            $months['05'] = 'May';
            $months['06'] = 'Jun';
            $months['07'] = 'Jul';
            $months['08'] = 'Aug';
            $months['09'] = 'Sep';
            $months['10'] = 'Oct';
            $months['11'] = 'Nov';
            $months['12'] = 'Dec';

            if ($datePieces[2] != '00' && $datePieces[1] != '00')
            {
                $datestring = $datePieces[2] . $delimiter 
                            . $months[$datePieces[1]] . $delimiter 
                            . $datePieces[0];
            }
            else if ($datePieces[1] != '00')
            {
                $datestring = $months[$datePieces[1]] . $delimiter 
                            . $datePieces[0];
            }
            else
            {
                $datestring = $datePieces[0];
            }

            return $datestring;

        }
        else
        {
            trigger_error('date is not in a valid mysql format');
            return false;
        }
    }
    else
    {
        trigger_error('empty date passed to format command');
        return false;
    }
}
