As seen in the first chapter, a string is a group of characters created by
|
|
surrounding text in single or double quotes.
|
|
```php
|
|
<?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.
|
|
```php
|
|
echo "Jacob\nJones\n";
|
|
```
|
|
|
|
Double quoted strings can also embed variables in the text. This code
|
|
outputs "Cindy Smith".
|
|
```php
|
|
$firstname = 'Cindy';
|
|
echo "$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.
|
|
```php
|
|
$firstname = 'Jenny';
|
|
$lastname = 'Madison';
|
|
$fullname = $firstname . $lastname;
|
|
echo $fullname;
|
|
```
