As seen in the first chapter, a string is a group of characters created by surrounding text in single or double quotes.
<?php $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.
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;
