In what scenarios would it be more beneficial to store user data in files on the server or on the client side, rather than in a database table?

Storing user data in files on the server or on the client side can be more beneficial in scenarios where the data is temporary, does not need to be accessed frequently, or does not require complex querying. This approach can be simpler and more lightweight than setting up a database table, especially for small-scale projects or when dealing with data that is not relational.

// Storing user data in a file on the server
$userData = [
    'name' => 'John Doe',
    'email' => 'john.doe@example.com',
    'age' => 30
];

$file = 'user_data.txt';
file_put_contents($file, json_encode($userData));

// Retrieving user data from the file
$data = file_get_contents($file);
$userData = json_decode($data, true);

echo $userData['name']; // Output: John Doe
