PHP is a widely used server scripting language. It’s vast capabilities and lightweight nature makes it ideal for web frontend developing, and while it is possible to create advanced structures in it, it’s basic usage also easy to learn, which makes it a good starting point for beginners also. The data recorded, processed, sent or displayed by the application we build is need to be stored somewhere, however; our webpage is stateless without this data. We can store our data in many ways or even discard it after use, but the most standard way is storing it in a database designed for the sole purpose of storing data in a reliable way, and present it if needed, as fast as possible.
In this tutorial we will build a simple webpage to record and display user data. We will use a PostgreSQL RDBMS as backend, and develop our application in PHP that will run on an Apache Webserver. This way we can access our web application from any common browser to view or add to our user database. It is the nature of the web application that many users/operators can work with it simultaneously, all they need is a browser and network access to our application.
In this tutorial you will learn:
- How to install needed packages for PostgreSQL connection in PHP
- How to create the database side of the application
- How to code the example application
- How to operate and verify the example application
