Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "To declare an event in your CComponent child class, you should add a method with a name starting with on."

A block of code is set as follows:

defined('YII_DEBUG') or define('YII_DEBUG', false);
defined('YII_TRACE_LEVEL') or define('YII_TRACE_LEVEL', 0);

$yii=dirname(__FILE__).'/../framework/yii.php';
$config=dirname(__FILE__).'/../app/config/production.php';

require($yii);

Yii::createWebApplication($config)->run();

Any command-line input or output is written as follows:

cd path/to/protected/tests
phpunit unit/BBCodeTest.php

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Now, go to the Gii controller generator and enter SecureController into the Base Class field."
