Lately I used the following snippet in all my webapps to secure them
against sql injection :

http://php.net/mysql_real_escape_string under "Best practice".

<?php
function smart_quote($value)
{
   // Stripslashes
   if (get_magic_quotes_gpc()) {
     $value = stripslashes($value);
   }
   // Protect it if it's not an integer
   if (!is_numeric($value)) {
     $value = "'" . mysql_real_escape_string($value) . "'";
   }
   return $value;
}

// Secure query
$sQuery = sprintf("SELECT *
                   FROM users
                   WHERE user=%s AND password=%s",
                   smart_quote($_POST['username']),
                   smart_quote($_POST['password']));
mysql_query($query);
?>

I think it is better than what we have now in AppDB (didn't check it
though). If nobody looks at it, I'll check the code after my master
thesis (in one month).
