What are the advantages of using arrays over numbered variables when processing data in PHP for database insertion?

When processing data for database insertion in PHP, using arrays over numbered variables allows for easier management and manipulation of multiple data points. Arrays provide a more organized way to store and access data, making it simpler to iterate through and insert into a database. This approach also helps to maintain code readability and scalability as the number of data points increases. 

// Using arrays for database insertion
$data = [
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'age' => 30
];

// Insert data into database using PDO
$stmt = $pdo->prepare("INSERT INTO users (name, email, age) VALUES (:name, :email, :age)");
$stmt->execute($data);
