✦ Synopsis

Learn to create web applications in PHP with minimal previous experience. This book is a practical guide to using PHP for web development.

Loaded with examples and step-by-step instructions, each chapter is dedicated to a specific area or function. You’ll first review the main principles of PHP and what is needed to program and develop in it. You’ll then study variables, data types, control statements, arrays, and functions, all critical for creating efficient PHP programs.

The book then moves on to object-oriented programming (OOP) and how to implement those principles in PHP, as well as inheritance, interfaces, testing, error handling, and exceptions. By the end of PHP by Example, you will have the knowledge and confidence to implement PHP for your web projects both large and small.

What You’ll Learn
Understand PHP from the ground up
Create scripts and implement them in real-world projects
Work with a broad toolkit of ready-made exercises and solutions
Investigate the main constructions of the PHP
