In this article, I ll bring you up to speed on the basic syntax of the PHP language, including variables, operators, and control structures. This article is the second in a series teaching PHP. Specifically, the goal of this series is to teach you all you need to know to create dynamic Web sites using PHP. This article picks up right where the previous article in the series, Getting Started with PHP, left off. Variables Here is the listing for the first PHP script I helped you create in the previous article: 1 2 3 My First PHP Page 4 5 6 10 11 As I admitted in that article, this is a pretty uninteresting example of an PHP script. When it comes right down to it, this script doesn t do anything a plain, old HTML page couldn t do. Oh sure, I gave a slightly more interesting example that displayed the current server time, but to be really useful a script needs to per some of calculation, or manipulate dynamic ination to present it in some interesting way. The language used for writing most PHP programs, and which I ll be using throughout this series, is called PHP . Like most programming languages, PHP lets you store data in variables. A variable may be thought of simply as a named location in memory where data may be stored. PHP is what is known as a loosely typed language, which means that a particular variable may store any kind of ination, be it a number, a piece of text, a date, or some more complicated chunk of data (as opposed to strictly typed languages where you can only store one kind of ination in each variable). Before you can use a variable, though, you must declare it; that is, you must let PHP know that you want to create a variable with a particular name. Let s look at a basic example to help solidify these concepts in your mind. Say you were writing a Web page that pered conversions between Celsius and Fahrenheit temperatures. In countries where Celsius is used, 20C is commonly accepted as the value for room temperature. The following code creates a variable calle
