How do you return an array from a function?

Returning an array is like returning any other type of variable in
PHP. They work great as parameters too. Here's an example:

function add_fruit($a, $b) {
return array($a, $b, 'cranberry');
}

$fruits = add_fruit('apple','banana');

foreach ($fruits as $key => $fruit) {
print "$key : $fruit <br>";
}

0 : apple <br>
1 : banana <br>
2 : cranberry <br>
