What are the advantages and disadvantages of storing user profile information in separate tables versus using arrays or self-defined structures in PHP?

Storing user profile information in separate tables allows for better organization, scalability, and easier retrieval of data. However, using arrays or self-defined structures in PHP can simplify the code and reduce the number of database queries needed. The choice between the two methods depends on the specific requirements of the project. 

// Storing user profile information in separate tables
$user_id = 1;
$query = "SELECT * FROM users WHERE id = $user_id";
$result = mysqli_query($connection, $query);
$user_profile = mysqli_fetch_assoc($result);

// Using arrays or self-defined structures in PHP
$user_profile = [
    'id' => 1,
    'username' => 'john_doe',
    'email' => 'john.doe@example.com',
    'age' => 30
];
