Use the PHP mysqli_connect() function to open a new connection to the MySQL server.
Open a Connection to the MySQL Server
Before we can access data in a database, we must open a connection to the MySQL server.
mysqlhotcopy Utility
The mysqlhotcopy utility is a perl script that uses several basic system and SQL commands to backup a database. More specifically, it will lock the tables, flush the tables, make a copy, and unlock the tables. Although it is the fastest method available for backing up a MySQL database, it is limited to backing up only those databases residing on the same machine as where it is executed.
MySQL Revoke Command
The REVOKE command is used to rescind privileges previously granted to a user. Its syntax is:
REVOKE priv_type [(column_list)] [, priv_type [(column_list)] ...]
ON {tbl_name | * | *.* | db_name.*}
FROM user_name [, user_name ...]
MySQL Grant Command
The GRANT function is used both to create new users, and to assign privileges to users. Its syntax is:
mysql>GRANT priv_type [(column_list)] [, priv_type [(column_list)] ...]
ON {tbl_name | * | *.* | db_name.*}
TO user_name [IDENTIFIED BY 'password']
[, user_name [IDENTIFIED BY 'password'] ...]
[WITH GRANT OPTION]
Securing a MySQL Database

Using mysqladmin
The mysqladmin program is used to administrate various aspects of the MySQL database server. Using it, the administrator can perform tasks such as: create and delete databases, shutdown the database server, update the privilege tables, and view running MySQL processes. The general syntax is:

Selecting a MySQL Database
Of course, simply connecting to the MySQL server isn’t going to accomplish much. Chances are you will want to select a database to work with. This is accomplished in one of two ways:
Connecting to the MySQL Server For the First Time
The MySQL client program, also known as the MySQL monitor, is an interface that allows the user to connect to the MySQL server, create and modify databases, and execute queries and view their results. This program is started by executing the command mysql at the shell prompt. In general, the syntax for this command is:
Understanding MySQL Configuration File
It’s very likely that the first task the administrator will want to undertake is proper configuration of MySQL’s configuration file. This file, entitled my.cnf, stores default startup options for both the server and for clients. Correct configuration of this file can go a long way towards optimizing MySQL, as various memory buffer settings and other valuable options can be set here.
