Multilanguage site question

How should i input language file into db and then output it with user selected language?

$username = 'KELLY';
$offerName = 'Crowd Flower';
$amount = '30';
$currency = 'points';
$lang['text']['a_001'] = '%a has just completed the %b offer worth %c %d.';// ENGLISH //

$input = str_replace(array('%a','%b','%c','%d'), array($username, $offerName, $amount, $currency), $lang['text']['a_001']);

print $input;

If it is a file, why do you need to store it in the database? If you are going to store in the DB, then you would want to store the data in separate fields for username, offername, etc.
