This is because pg_query() returns false on error instead of the

Recently, there has been a strong trend towards providing web-based interfaces to online databases. There are a number of reasons supporting this movement, including: Web browsers are common and familiar interfaces for browsing data Web-based applications can easily be integrated into an existing web site Web (HTML) interfaces are easily created and modified In this chapter, we will explore various methods for accessing PostgreSQL from PHP. PHP is a server-side, cross-platform scripting language for writing web-based applications. It allows you to embed program logic in HTML pages, which enables you to serve dynamic web pages. PHP allows us to create web-based user interfaces that interact with PostgreSQL. In this chapter, we will assume at least a basic understanding of the PHP language. If you are completely unfamiliar with PHP, you might want to explore some of the following resources first: The home site of PHP http://www.php.net Beginning PHP 4, Wankyu Choi, Allan Kent, Ganesh Prasad, and Chris Ullman, with Jon Blank and Sean Cazzell, Wrox Press (ISBN 1-861003-73-0) There are many different schools of thought concerning PHP development methodologies. It is not within the scope of this book to discuss them. Instead, we will focus on designing PHP scripts that make effective use of PHP's PostgreSQL interface. Note that we will be focusing on PHP version 4. While most of the following code examples and descriptions will apply to earlier versions of PHP, there may be a few differences in functionality. In addition, it is assumed that all code snippets fall within the context of valid PHP scope (generally meaning with the tags), unless otherwise specified. Adding PostgreSQL Support to PHP Before you can begin developing PHP scripts that interface with a PostgreSQL database, you will need to include PostgreSQL support in your PHP installation. If you're not sure whether your existing PHP installation already has PostgreSQL support, create a simple script named phpinfo.php (which should be placed in yo
