It's just another way of doing things. In programming there are often
multiple ways of doing things, i.e. (to add to the book example)

$fruits = array("d" => "lemon", "a" => "orange", "b" => "banana", "c" =>
"apple");

function test_print($item2, $key)
{
echo "$key. $item2<br />\n";
}

// As a foreach loop:

foreach($array as $key->$value)
test_print($value, $key);

// Or, with array_walk)
array_walk($fruits, 'test_print');
