This should work, just adapt it to your code by replacing the variables, table and column nammes with yours.

$sql = 'SELECT text FROM table WHERE id='.$id;

$result = mysql_query($sql, $conn) or die('SQL error');
$text = mysql_result($result);

header('Content-Type: text/plain');
echo $text;

Note, that you should not output any HTML or whitespace before sending the header, though.

Hope this helps.
