<?php

// As seen in the first chapter, a string is a group of characters created by
// surrounding text in single or double quotes.
$firstname = 'Joey';
$lastname = "Johnson";

// A double quoted string can interpret special characters starting
// with a back slash to create formatting. The \n creates a newline
// between the names and after them.
echo "Jacob\nJones\n";

// Double quoted strings can also embed variables in the text. This code
// outputs "Cindy Smith".
$firstname = 'Cindy';
echo "$firstname Smith\n";

// Another feature of strings is the ability to combine them together.
// To combine two strings, use the period character in between them.
$firstname = 'Jenny';
$lastname = 'Madison';
$fullname = $firstname . $lastname;
echo $fullname;
