+// 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;
