You Want to make like this

Array
(
    [book] => Array
        (
            [0] => Array
                (
                    [name] => Java
                    [author] => Rao
                    [@attributes] => Array
                        (
                            [x] => 1
                            [y] => 2
                        )

                )

            [1] => Array
                (
                    [name] => Php
                    [author] => Naidu
                    [@attributes] => Array
                        (
                            [x] => 12
                            [y] => 20
                        )

                )

            [2] => Array
                (
                    [name] => Xml
                    [author] => Gowda
                    [@attributes] => Array
                        (
                            [x] => 19
                            [y] => 29
                        )

                )

        )

)

So just place you array inside "pre" tags.
Like this :

echo "<pre>";
print_r($array);
echo "</pre>";
