38 Chapter 3 ■ How to Write PHP Scripts Data Types in PHP PHP is what’s known as a weakly typed language. , Java or C#), PHP doesn’t care what type of data you store in a variable. Most of the time, this is very convenient, although you need to be careful with user input. You may expect a user to enter a number in a form, but PHP won’t object if it encounters a word instead. Checking user input carefully is one of the major themes of later chapters. Even though PHP is weakly typed, it uses the following eight data types: • Integer: This is a whole number, such as 1, 25, 42, or 2006.

Are they both the same? And so on. To test for equality, PHP uses two equal signs (==), like this: if ($status == 'administrator') { // send to admin page } else { // refuse entry to admin area } ■■Caution Don’t use a single equal sign in the first line ($status = 'administrator'). Doing so opens the admin area of your website to everyone. Why? Because this automatically sets the value of $status to administrator; it doesn’t compare the two values. To compare values, you must use two equal signs.

They are case-insensitive. Making Decisions Decisions, decisions, decisions. . Life is full of decisions. So is PHP. They give it the ability to display different output according to circumstances. Decision-making in PHP uses conditional statements. The most common of these uses if and closely follows the structure of normal language. In real life, you may be faced with the following decision (admittedly not very often if you live in Britain): If the weather’s hot, I’ll go to the beach. In PHP pseudo-code, the same decision looks like this: if (the weather's hot) { I'll go to the beach; } 29 Chapter 3 ■ How to Write PHP Scripts The condition being tested goes inside parentheses, and the resulting action goes between curly braces.
