What are the advantages and disadvantages of storing data in arrays versus databases in PHP applications?

Storing data in arrays in PHP applications can be advantageous for small datasets as it is simple and fast to access elements. However, for larger datasets or when data needs to be persisted across sessions, using databases is more efficient and allows for easier querying and data manipulation. 

// Example of storing data in an array
$data = [
    ['id' => 1, 'name' => 'John'],
    ['id' => 2, 'name' => 'Jane'],
];

// Example of storing data in a database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
$stmt = $pdo->prepare("SELECT id, name FROM users");
$stmt->execute();
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
