PHP - Classes and Objects

Given this class:

class Book {
  public $title;
  public $author;
  public function __construct($title, $author) {
    $this->title = $title;
    $this->author = $author;
  }
}

// Create an array of books with titles and authors
$booksData = [
  ['1984', 'George Orwell'],
  ['Brave New World', 'Aldous Huxley'],
  ['Fahrenheit 451', 'Ray Bradbury']
];

// Fill this array with Book objects
$books = [];
foreach ($booksData as $data) {
  // Fill here
}

Which line correctly creates and adds a new Book object to $books inside the loop?

A$books[] = new Book($data[1], $data[0]);

B$books[] = new Book($data[0], $data[1]);

C$books[] = new Book($data);

D$books[] = Book($data[0], $data[1]);

Step-by-Step Solution

Solution:

Step 1: Understand constructor parameters
The constructor expects two parameters: title and author, in that order.
Step 2: Match data array to constructor
$data[0] is title, $data[1] is author, so new Book($data[0], $data[1]) is correct.
Step 3: Add object to array
Using $books[] = appends the new object to the array.
Final Answer:
$books[] = new Book($data[0], $data[1]); -> Option B
Quick Check:
Use new with correct params and append [OK]

Quick Trick: Match constructor params order exactly when using new [OK]

Common Mistakes:

Omitting new keyword
Passing whole array instead of separate params
Swapping title and author order
