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: "Let's set up our listener.php file to store all incoming messages and messages.php to view messages we've received."

A block of code is set as follows:

  <?php
    $accountsid = '';  //  YOUR TWILIO ACCOUNT SID
    $authtoken = '';  //  YOUR TWILIO AUTH TOKEN
    $fromNumber = '';  //  PHONE NUMBER CALLS WILL COME FROM
    $myUrl = '';    //  THE URL TO YOUR SCRIPT

    $dbhost = '';    //  YOUR DATABASE HOST
    $dbname = '';    //  YOUR DATABASE NAME
    $dbuser = '';    //  YOUR DATABASE USER
    $dbpass = '';    //  YOUR DATABASE PASS
  ?>

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: "We now have a menu option under the Admin menu called Test Call Flow."
