How can PHP developers effectively utilize databases like MySQL to manage user registration information?

PHP developers can effectively utilize databases like MySQL to manage user registration information by creating a database table to store user data, establishing a connection to the database using PHP, inserting user registration information into the database table, and querying the database to retrieve user information when needed. 

// Establish a connection to the MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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

// Insert user registration information into the database
$username = "user123";
$email = "user123@example.com";
$password = "password123";

$sql = "INSERT INTO users (username, email, password) VALUES ('$username', '$email', '$password')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

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