A four part tutorial that explains the PHP / MySQL extensions - mysql, mysqli, and pdo_mysql - with simple examples is now accessible from Sun Developer Network. While most of the information presented in the tutorial is available elsewhere in bits and pieces, the real value-add is in the introduction of the MySQL native driver for PHP, mysqlnd.

Here is a brief description of all four parts in the series:

• Part 1: Using the MySQL Improved Extension, mysqli -- describes mysqli, the MySQL Improved Extension that is the successor to the mysql extension
  
  
• Part 2: Using the MySQL Extension, mysql -- describes the original extension designed to develop PHP applications that interact with a MySQL database
  
  
• Part 3: Using the PDO Extension With MySQL Driver, pdo_mysql -- describes the pdo_mysql driver, which implements the PHP Data Objects (PDO) interface to access the MySQL Server from PHP
  
  
• Part 4: Using the MySQL Native Driver for PHP, mysqlnd -- describes the MySQL native driver for PHP, mysqlnd, which is an alternative to the MySQL client library, libmysql, for connecting from PHP 5 and PHP 6 to MySQL Server 4.1 or later

Application developers who are new to the development of MySQL database applications with PHP are the target audience of this tutorial.
