MySQL Versus MySQLi Functions

If you have used previous versions of PHP, or current versions of PHP with older versions of MySQL, you likely are familiar with the mysql_* family of functions. However, since the release of MySQL 4.1.3 it has become necessary to communicate with MySQL using the mysqli_* family of functions. All code in this chapter, and throughout the rest of this book, uses the mysqli_* family of functions. For more information, see the PHP Manual chapter at http://www.php.net/mysqli.
