Hvordan gemmer man europæisk valuta i MySQL?

du kan gemme det som et almindeligt decimalfelt i databasen og formatere tallet europæisk stil, når du viser det

edit:har lige tilføjet et eksempel på, hvordan det kan opnås

$european_numbers = array('123.345,78', '123 456,78', ',78');

foreach($european_numbers as $number) {

    echo "$number was converted to ".convert_european_to_decimal($number)."\n";
    // save in database now
}

function convert_european_to_decimal($number) {
    // i am sure there are better was of doing this, but this is nice and simple example
    $number = str_replace('.', '', $number); // remove fullstop
    $number = str_replace(' ', '', $number); // remove spaces
    $number = str_replace(',', '.', $number); // change comma to fullstop

    return $number;
}
