597Chapter 23Running a Linux, Apache, MySQL, and PHP (LAMP) Serverconsists of a server that handles storage and access to data and clients to handleinterfacing with and managing the server. Client libraries are also included, andthey can be used by third-party programs, such as PHP, to connect to the server. In a LAMP server, MySQL is used for storing data appropriate to the Web applicationsthat are being used. Common uses include data such as usernames and passwords, entries in a journal, and data files. Data within a database are stored in tables; each table contains columns and rows. You could compare a table to a spreadsheet, in which each column contains aspecific data field and each row contains a record. Instead of a graphical represen- tation of the data, individual rows are accessed using a query that returns only therows desired. MySQL was originally developed by Michael (Monty) Widenius of TcX (Sweden). In1994, TcX needed a backend database for Web applications and decided to use onesupporting SQL, a standardized and widely recognized language for interacting withdatabases. TcX investigated the free databases that were available at the time, plus some commercial databases, but could not find a system that supported the features itneeded and could handle its large databases at the same time. Because it alreadyhad experience writing database programs, TcX decided that the best way to getwhat it wanted was to develop a new system that supported SQL. In 1995, TcX released the source code for MySQL on the Internet. MySQL was notanopen source program at that time (due to some of the restrictions in its license), but it still began to see widespread use. MySQL was later released under the GNUGeneral Public License (GPL). PHPPHP is a programming language that was developed specifically for use in Webscripts. It is preferred by many developers because it s designed to be embeddedwithin HTML documents, making it simpler to manage Web content and scriptswithin a single file. PHP originated as a set of Perl scripts by Rasmus Lerdorf called PHP/FI (PersonalHome Page/Forms Interpreter).Over time, more features were implemented, andRasmus rewrote PHP/FI in C. In late 1997, Andi Gutmans and Zeev Suraski began working on a complete rewriteof PHP/FI. As the language evolved and more features were implemented, Gutmansand Suraski decided that it would be appropriate to rename the project to moreaccurately reflect these features. The name PHP Hypertext Preprocessor (PHP) was chosen, with Lerdorf s approval, to maintain familiarity for users of PHP/FI. Note32_
