For example, if you wanted to add an extra line to this example, where $name is set, and weren’t paying close attention, you might write it like this: if(isset($name)) echo “Hello $name”; $known_user = true; This code would not at all do what you intended. Therefore, to avoid confusion, you should always use braces, even when only a single statement is being conditionally executed: if(isset($name)) { echo “Hello $name”; } else { echo “Hello Stranger”; } Consistently Using Braces You need to choose a consistent method for placing braces on the ends of conditionals.

You must also choose the tab width that you want to use. I have found that a tab width of four spaces produces code that is readable and still allows a reasonable amount of nesting. Because book pages are somewhat smaller than terminal windows, I use two space tab-widths in all code examples in this book.
