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: "Create a file named query_log.php and place it in your app/controllers/components folder with the following contents:"

A block of code is set as follows:

CREATE TABLE `accounts`(
`id` INT UNSIGNED AUTO_INCREMENT NOT NULL,
`email` VARCHAR(255) NOT NULL,
PRIMARY KEY(`id`)
);

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: "In that screen, make sure to grab what is shown as Consumer key and Consumer secret, as we will need it when going through this recipe."
