Multidimensional Array

I have an array, I want to be able to access the array like this...

Code:

---

$book['author'][0]

---

But it wont let me access the array, any reason why? I have to be able to access using its name, author, title etc.

Code:

---

(
    [0] => Array
        (
            [0] => author
            [1] =>
            [2] =>
            [3] => 1
        )

    [1] => Array
        (
            [0] => year_of_publication
            [1] =>
            [2] =>
            [3] => 1
        )

    [2] => Array
        (
            [0] => title
            [1] => <em>
            [2] => </em>
            [3] => 1
        )

    [3] => Array
        (
            [0] => edition
            [1] =>
            [2] =>
            [3] =>
        )

    [4] => Array
        (
            [0] => publisher
            [1] =>
            [2] =>
            [3] => 1
        )

)

The array is an indexed array and therefore must be accessed with indexes i.e: 0,1,2,3 . It is difficult from what you have shown above where the data has come from. Is it a regular expression?

I physically make the array further up in the script, here it is...

Code:

---

// field, prefix, suffix, required
$book = array(
        array('author', '', '', true),
        array('year_of_publication', '', '', true),
        array('title', '<em>', '</em>', true),
        array('edition', '', '', false),
        array('publisher', '', '', true)
);

Author is a key. So use the => operator to specify this in your top level array:

Code:

---

$book = array (
    'author' => array('','',true) ...
...
...
