What are the potential drawbacks of creating a separate PHP profile file for each user upon registration?

Creating a separate PHP profile file for each user upon registration can lead to scalability issues as the number of users grows, potentially causing performance issues and increased storage requirements. A more efficient approach would be to store user profile information in a database and retrieve it as needed. 

// Example of storing user profile information in a database table

// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database');

// Insert user profile information into the database
$username = 'example_user';
$email = 'example@example.com';
$age = 25;

$sql = "INSERT INTO user_profiles (username, email, age) VALUES ('$username', '$email', $age)";
$connection->query($sql);

// Retrieve user profile information from the database
$user_id = 1;

$sql = "SELECT * FROM user_profiles WHERE id = $user_id";
$result = $connection->query($sql);

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "Username: " . $row['username'] . "<br>";
        echo "Email: " . $row['email'] . "<br>";
        echo "Age: " . $row['age'] . "<br>";
    }
} else {
    echo "User profile not found.";
}

// Close the database connection
$connection->close();
