CodeIgniter is an easy-to-pick-up framework written in PHP; so, familiarity with PHP and CodeIgniter is advantageous. But, having no experience with CodeIgniter shouldn't be a road block to read the book either. The best thing to do (if you're unsure) is to buy it and just jump in. Having said that, if you are familiar with CodeIgniter, this book can provide immediate sold snippets and recipes you can use for all sorts of day-to-day, CodeIgniter-related tasks.

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: " The public function index() function redirects us to the function public function send_mail()."

A block of code is set as follows:

$this->email->from('[email protected]', 'Your Name');
$this->email->to('[email protected]');

$this->email->subject('This is a text email');
$this->email->message('And this is some content for the text email.');

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 __construct() {
    parent::__construct();
    $this->load->helper('url');
    $this->load->library('email');
}

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

C:\path\to\CodeIgniter\file.htaccess" .htaccess

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 user clicks on View Cart to view the products they wish to order".
