Why is it recommended to use databases instead of file systems for user data storage in PHP applications, according to the forum discussion?

Using databases for user data storage in PHP applications is recommended over file systems because databases provide better security, scalability, and organization of data. Databases offer features like encryption, user authentication, and access control, which are crucial for protecting sensitive user information. Additionally, databases allow for efficient querying and indexing of data, making it easier to retrieve and manipulate user data as needed. 

// Example PHP code snippet using a MySQL database for user data storage

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Query database for user data
$sql = "SELECT * FROM users";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["name"]. " - Email: " . $row["email"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
