Building Web Applications in PHP

Building dynamic and interactive web applications is an essential skill in today’s digital world.

Whether you're creating a personal project or developing a commercial website, understanding how to use PHP alongside other key technologies is crucial.

This course is part of the Web Applications for Everybody Specialization, designed to equip you with foundational knowledge of PHP, HTML, CSS, and web server interaction.

Overview of Web Application Structure

In this course, you’ll dive into the fundamental structure of web applications, learning how a web browser communicates with a web server.

The core concepts of the request/response cycle are covered, including the essential HTTP methods such as GET, POST, and Redirect. Understanding how data flows between a client and server is vital for building responsive and user-friendly applications.

PHP Basics: Syntax and Data Structures

Mastering PHP is central to this course. You will learn the basic syntax and core data structures, such as variables, logic, iteration, arrays, and error handling.

Additionally, superglobal variables—unique to PHP—will be introduced. These are powerful tools in managing user input and server responses.

Gaining confidence in these areas will allow you to write more efficient, scalable code.

Setting Up the Development Environment

Before you can start coding, setting up a local development environment is necessary.

You’ll gain the skills to install and configure an integrated PHP/MySQL environment like XAMPP or MAMP.

This will enable you to build, test, and run your web applications locally before deploying them to a live server.

Key Topics You Will Learn
