Array question

[TomTees]

I have a question about the array in this code...

 

class Model {

public function getBookList()

{

return array(

"Jungle Book" => new Book("Jungle Book", "R. Kipling", "A classic book."),

"Moonwalker" => new Book("Moonwalker", "J. Walker", ""),

"PHP for Dummies" => new Book("PHP for Dummies", "Some Smart Guy", "")

);

}

}

 

class Book {

public $title;

public $author;

public $description;

 

public function __construct($title, $author, $description) 

    { 

$this->title = $title;

    $this->author = $author;

    $this->description = $description;

    }

}

 

 

Questions:

--------------

1.) Is it correct that in the array above, the KEY is a book name and the VALUE is an object?

 

2.) What is the name of the array above?

1. Yes

 

2. It has no name, you could give it a name only this way:

 

$theNameOfTheArray = $model->getBookList

Why not give the anonymous array a name like this...

 

class Model {

public function getBookList()

{

$myArray = array(

"Jungle Book" => new Book("Jungle Book", "R. Kipling", "A classic book."),

"Moonwalker" => new Book("Moonwalker", "J. Walker", ""),

"PHP for Dummies" => new Book("PHP for Dummies", "Some Smart Guy", "")

);

return $myArray;

}

}

You could, but there is no reason to. The name $myArray will only exist inside the method. Once the return is executed and you leave the method, that name would no longer exists.

1.) Is it correct that in the array above, the KEY is a book name and the VALUE is an object?

 

Your duplicating data this way. I would make it a simple numerically indexed array.

 

2.) What is the name of the array above?

 

Arrays don't have names. They can be stored in variables, but I'm not sure that is what you meen.

I'm just working off a tutorial on MVC and trying to understand it.

Arrays don't have names. They can be stored in variables, but I'm not sure that is what you mean.

 

I'm used to seeing array being assigned to a variable when they are created.
