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: " You can protect it either by using an .htaccess file or by placing the directory outside the web server's documents directory."

A block of code is set as follows:

<?php  /// Moodle Configuration File

unset($CFG);

$CFG->dbtype    = 'mysqli';
$CFG->dblibrary = 'native';
$CFG->dbhost    = 'localhost';
$CFG->dbname    = 'info-overload';

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: " The contents of the Administration menu change depending upon who is logged in ".
