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 are shown as follows: "Finally, we display our table using the print_html member function"

A block of code is set as follows:

<?php
function learningisfunlink_filter($courseid, $text) {
return $text;
}
?>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

function get_content() {
if ($this->content !== NULL) {
return $this->content;
}//if
$context = get_context_instance(CONTEXT_SYSTEM); require_capability('moodle/site:doanything', $context); 
$this->content = new stdClass;
$this->content->text = 'Hello World!';
return $this->content;
}//function get_content

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: "Click on the Notifications link in the Site Administration block."
