Let's begin with the definitions of PHP and MySQL for those now as versed in the Web Design World...
PHP is a scripting language for Web development that is easily embedded into web pages, with the ability to access and provide information from web-hosted databases. Because it is an open source language, it is a free and available language which, in turn, reduces the overhead cost of programming for the Web. For more information: http://www.php.net.
MySQL is a database technology for web sites that, like PHP, is open source, and therefore free of charge and a reducer of overhead costs for web site owners. It's not the only open source database system, just the most popular and quite possibly the most efficient, in use by millions of businesses and organizations.

PHP and MySQL progrramming are included in the initial design of a WSC Web Site, but additional charges may apply for programming work performed after the site completion, and may also be retained on a consultant basis for particular tasks such as script repair. Rates may vary based upon the specific project. Please contact WSC for details.
