To close your MySQL database connection you need to use the mysql_close() function. Please see the example below: <?php mysql_close(); ?> If your connection data is stored in a variable you would close the connection like this instead: <?php mysql_close($db_conn); ?> That's useful for if you're using more than one database connection in a PHP script.

how do u develop software using php and mysql?
By sending messages to the MySQL server, you can communicate with the database. To submit SQL queries to the database, you use PHP functions. You don't need to know how to communicate with MySQL because PHP takes care of that. You only need to be familiar with SQL queries and PHP functions.

Ultimately PHP is a programming language and MySQL is a database language. Using PHP with MySQL is a nice combination with built-in support and the simplicity of it all. However, there aren't a lot of disadvantages of using PHP with a database, it just allows for better data organization and whatnot. There are definitely advantages and disadvantages to using a database other than MySQL (such as MongoDB or PostgreSQL).
You don't. PHP does not required MySQL to function. But because PHP is one of the easiest language with more built-in functions than you would ever need, and MySQL is free and easy to manage; people often use them together :)
