Learning PHP, MySQL, andJavaScript: A Step-by-Step Guide to Creating Dynamic Websites Product Description
If you know HTML, this guide will have you building interactive websites quickly. You’ll learn how to create responsive, data-driven websites with PHP, MySQL, and JavaScript, regardless of whether you already know how to program. Discover how the powerful combination of PHP and MySQL provides an easy way to build modern websites complete with dynamic data and user interaction. You’ll also learn how to add JavaScript to create rich Internet applications and websites.
Learning PHP, MySQL, and JavaScript explains each technology separately, shows you how to combine them, and introduces valuable web programming concepts, including objects, XHTML, cookies, and session management. You’ll practice what you’ve learned with review questions in each chapter, and find a sample social networking platform built with the elements introduced in this book. This book will help you:
- Understand PHP essentials and the basics of object-oriented programming
- Master MySQL, from database structure to complex queries
- Create web pages with PHP and MySQL by integrating forms and other HTML features
- Learn about JavaScript, from functions and event handling to accessing the Document Object Model
- Use libraries and packages, including the Smarty web template system, PEAR program repository, and the Yahoo! User Interface Library
- Make Ajax calls and turn your website into a highly dynamic environment
- Upload and manipulate files and images, validate user input, and secure your applications

Learn How to Program Using Any Web Browser is a book about general principles of good programming practice for complete novices. If you’re a teen or someone who is just starting to get curious about what makes a computer work, or an office worker who has been using computer applications for years and would like to spend some time looking deeper into what makes them tick, then this book is for you.
Learn How to Program Using Any Web Browser teaches the basics of programming using JavaScript. JavaScript, a modern programming language, can be written using any text editor and displayed in almost any web browser, regardless of the operating system. In the process, author Harold Davis discusses modern computer programming principles and explains concepts such as object-oriented programming in an easy-to-understand manner.
Objects, objects everywhere: But what are they and how do they work? The move to object-oriented programming-called “OO” or “OOP” when you want to use an acronym-has been one of the most important trends in the programming community over the past 10 or 20 years.
This chapter addresses a number of interrelated topics, each of which is important in its own right.
To start with, what is object-oriented programming? Why is it important? What is an object? How do objects and classes relate? The focus of this book is about learning how to program and the craft of programming. It’s definitely not about the ins and outs of JavaScript. JavaScript is used as a teaching language-because it’s good to be able to see the consequences of one’s work in action.
That said, it’s still worth spending some time understanding how objects work in JavaScript. What are the objects built into JavaScript? How can you effectively use JavaScript objects? (I’ve called the section of this chapter that explicitly addresses these issues “JavaScript OO Lite.”) It turns out that JavaScript contains some OO features but isn’t fully OO in the ways that languages such as C# and Java are. (For one thing, there’s no explicit notion of a class, or object template, in JavaScript, as I explain in more detail later in this chapter.) However, it also turns out that one can program in a very OO fashion in a not-very-OO language-just as one can skip the OO and bang out straight procedural code in an OO language such as C# or Java. (By the way, I really don’t recommend the latter of these practices.)
We’ll take the leap with JavaScript and use its features to understand the essential points of object-oriented programming in general and specifically how to implement OO in JavaScript. How do you create and modify your own objects in JavaScript? How are objects best used in your programs? JavaScript may not have classes, but, as I’ll show you, it does have prototypes, which are used to manage object inheritance. How does a prototype differ from a class, and why should you care? How can you work with prototypes in JavaScript to get a good feeling for the power of classes and inheritance generally?
By the end of this chapter you’ll be speaking, squeaking, dreaming, and rolling in objects-and, most important, you’ll have learned to think like an object-oriented programmer.

This course will NOT be dealing with programming fundamentals, or rigorous programming structures within JavaScript. That topic is far too broad for a two-hour introduction to JavaScript.
It’s important to understand the difference between Java and JavaScript. Java is a full programming language developed by Sun Microsystems with formal structures, etc. JavaScript is a scripting language developed by Netscape that is used to modify web pages. Most JavaScript must be written in the HTML document between <SCRIPT> tags. You open with a <SCRIPT> tag, write your JavaScript, and write a closing </SCRIPT> tag. Sometimes, as an attribute to script, you may add “Language=JavaScript” because there are other scripting languages as well as JavaScript that can be used in HTML. We’ll go through some examples to demonstrate the syntax of JavaScript.
To understand the workings of JavaScript, it is essential to understand a few basic programming concepts. JavaScript is object-oriented. An Object in JavaScript is a resource that has specific characteristics known as properties and provides several services known as methods and events. An example of an object is document, which represents the current web page and has properties such as location ( which stores the URL location of the document) and methods such as writeln , which writes dynamically created html text to the document
A variable stores a value. It can be thought of as a labeled box, with the name of the variable as the label and the value as the contents. The JavaScript statement:
var x= “hello”;
assigns to the variable named x the String value “hello”.
var x=1;
This line of JavaScript assigns to the variable x the integer value 1. As you can see, a JavaScript variable can refer to a value of any type; this can be integer, string, or even any type of object. You dont have to specify the type of variable before creating it. Note that object properties can be thought of as variables that belong to the object.
A method is basically a collection of statements that does something. For example, a method “writeln()” exists in the document object that can be used to write html to your document. Methods are predefined in JavaScript. It is possible for you to define functions, which can be thought of as methods you define outside of any object.
When you have the syntax object.method as you do with document.writeln, the method operates on the object given. In this case, the writeln method operates (the operation is writing) to the document (the browser window that you see). This syntactic structure is often used in JavaScript.
