How to create User in Mysql

Create new user in Mysql

We can create MySQL accounts in two ways, By using statements such as Create user and Grant.

1.CREATE USER

Syntax

CREATE USER 'user_name'@ 'host_name' [IDENTIFIED BY [PASSWORD] 'password']

Example

CREATE USER 'senthil'@ 'localhost' identified by 'admin';

Note

It must be noted that CREATE USER command was added in the MySQL version 5.0.2. In earlier versions, users could be created automatically when assigning permissions using the GRANT command or by manually inserting records in the mysql database.

2.Grant User

Syntax

GRANT [PRIVILIAGES] ON 'database_name'.'table_name' TO ''user_name'@ ''host_name' IDENTIFIED BY 'password';

Example

GRANT ALL ON 'test'.* TO ''senthil'@ ''localhost' IDENTIFIED BY 'admin';

To see a list of the userd and their privileges.

use mysql;

select * from mysql.user where User='user' \G;

HIstory of PHP

2009-04-17T22:56:00.000-07:00

What is PHP?

PHP is a great scripting language that can be used to create amazing forms, features, and functions on
your website. PHP is a widely used general-purpose scripting language that is especially suited for web
development and can be embedded into HTML. It generally runs on a web server, taking PHP code as
its input and creating web pages as output. It can be deployed on most web servers and on almost every
operating system and platform free of charge. PHP is installed on more than 20 million websites and 1
million web servers. The most recent major release of PHP was version 5.2.6 on May 1, 2008.
PHP originally stood for Personal Home Page. It began in 1994 as a set of Common Gateway
Interface binaries written in the C programming language by the Danish/Greenlandic programmer
Rasmus Lerdorf. Lerdorf initially created these Personal Home Page Tools to replace a small set of Perl
scripts he had been using to maintain his personal homepage.

Zeev Suraski and Andi Gutmans, two Israeli developers at the Technion IIT, rewrote the parser in 1997
and formed the base of PHP 3, changing the language's name to the recursive initialism PHP: Hypertext
Preprocessor.

PHP 4, powered by the Zend Engine 1.0, was released.
PHP 5 included new features such as improved support for object-oriented programming
In 2008, PHP 5 became the only stable version under development. Late static binding has been
missing from PHP and will be added in version 5.3.
PHP 6 is under development alongside PHP 5. Major changes include the removal of register_globals,
magic quotes, and safe mode.
PHP does not have complete native support for Unicode or multibyte strings; unicode support will be
included in PHP 6.
