Introducing PHP
Learn the Most Popular Server-Side Language
PHP is the most popular server-side language used to build dynamic websites, and though it is not especially difficult to use, non-programmers often find it intimidating. This workshop from author and trainer David Powers is designed to change that by teaching you PHP through a series of clear, focused, easy-to-follow lessons. After briefly explaining what PHP is and how it integrates with HTML, David will guide you through the setup and configuration of a PHP development environment on both Windows and Mac OS X. Then you’ll learn the features of the PHP language through a series of hands-on exercises before embarking on a larger project that involves building a script to validate and email user input from an online form. Through this project you’ll come to understand the value of creating reusable code, the importance of PHP security, and how to deal with multiple-choice form fields.
This workshop will introduce you to PHP, the most popular server-side language used to build dynamic websites. The contents of this course include:
Setting Up a PHP Development Environment
In this chapter you’ll learn how to install and configure a PHP testing environment on your local computer, with instructions for both Windows and Mac OS X.
PHP Basics
This chapter lays the foundation for working with PHP by describing the basic building blocks of the language.
Using Control Structures and Loops
This section dives deeper into the structure of PHP, explaining how to perform different actions based on conditions and comparisons, as well as how to use loops for repetitive actions and accessing the contents of an array.
Functions, Objects, and Errors
This chapter looks at using PHP’s built-in functions and objects with the help of the PHP online manual. You’ll also learn how to create your own custom functions and how to decipher PHP’s often cryptic error messages.
Emailing the Contents of an Online Form
This chapter steps you through the process of building a reusable script to validate and email user input from an online form.
Dealing with Multiple-Choice Form Fields
This chapter builds on the mail processing script created in the previous chapter.
The lessons are wrapped in a feature-rich interface that lets you jump to any topic and bookmark individual sections for later review. Full-Screen mode provides a hi-def, immersive experience, and Watch-and-Work mode shrinks the video into a small window so you can play the videos alongside your application. Also included are exercise files that give you an easy way to try out the techniques you learn.
