i always encrypted password with plus stringex:$pass = $_POST['t_password'];$en_pass=md5($pass . "string");

user is not permitted access to mysql configuration, so user cannot make a replication database.

if you are a databases administrator, u can create replication database.

i think, u make a coding that if u manipulation database, u should insert/update/delete to other database.

example : u have database_1 on host1.mysql.uk and database_2 on host2.mysql.org

u make coding where u your program connect to host1.mysql.uk & host2.mysql.org.

if u manipulate your data, each database must be manipulated too.

u should save to innodb (not myISAM) , why ??

because you must use procedure / transaction (commit, rollback)

many people use mysql & postgresqli like postgresql, i use it
