Overview of this book

PostgreSQL is the most advanced open source database in the world. It is easy to install, configure, and maintain by following the documentation; however, it’s difficult to develop applications using programming languages and design databases accordingly. This book is what you need to get the most out of PostgreSQL You will begin with advanced SQL topics such as views, materialized views, and cursors, and learn about performing data type conversions. You will then perform trigger operations and use trigger functions in PostgreSQL. Next we walk through data modeling, normalization concepts, and the effect of transactions and locking on the database. The next half of the book covers the types of indexes, constrains, and the concepts of table partitioning, as well as the different mechanisms and approaches available to write efficient queries or code. Later, we explore PostgreSQL Extensions and Large Object Support in PostgreSQL. Finally, you will perform database operations in PostgreSQL using PHP and Java. By the end of this book, you will have mastered all the aspects of PostgreSQL development. You will be able to build efficient enterprise-grade applications with PostgreSQL by making use of these concepts

Preface

Chapter 10. Using PHP in PostgreSQL

In the previous chapter, we covered what an extension is and how it's useful. We also covered how to create an extension and compile an extension that is not available by default. Additionally, we also talked about the dblink extension and how it is useful in the real world. The examples that we described gave you a better understanding of how those work and how to use them. In this chapter, we will work on PHP with Postgres. We start with a simple connection to Postgres with PHP and then talk about how to use DDLs, DMLs, and fetching data. We will talk about the available functions of PHP when working with SQLs.
