// Displays form for creating a table (if user has privileges for that)
require_once('./libraries/check_user_privileges.lib.php');
// for MySQL >= 4.1.0, we should be able to detect if user has a CREATE
// privilege by looking at SHOW GRANTS output;
// for < 4.1.0, it could be more difficult because the logic tries to
// detect the current host and it might be expressed in many ways; also
// on a shared server, the user might be unable to define a controluser
// that has the proper rights to the "mysql" db;
// so we give up and assume that user has the right to create a table
//
// Note: in this case we could even skip the following "foreach" logic
// Addendum, 2006-01-19: ok, I give up. We got some reports about servers
// where the hostname field in mysql.user is not the same as the one
// in mysql.db for a user. In this case, SHOW GRANTS does not return
// the db-specific privileges. And probably, those users are on a shared
// server, so can't set up a control user with rights to the "mysql" db.
// We cannot reliably detect the db-specific privileges, so no more
// warnings about the lack of privileges for CREATE TABLE. Tested
// on MySQL 5.0.18.
