572 CHAPTER (Web server extensions) 23 INTRODUCING PDO Summary PDO
572 CHAPTER 23 INTRODUCING PDO Summary PDO offers users a powerful means for consolidating otherwise incongruous database commands, allowing for an almost trivial means for migrating an application from one database solution to another. Furthermore, it encourages greater productivity among the PHP language developers due to the separation of language-specific and database-specific features. If your clients expect an application that allows them to use a preferred database, you re encouraged to keep an eye on this new extension as it matures in the coming months. The next chapter begins the detailed introduction to the PostgreSQL database server. From there you ll learn all about PostgreSQL installation and configuration, table structures, datatypes, and a variety of other pertinent topics. This sets the stage for several chapters discussing how PHP and PostgreSQL are most effectively integrated.
