CREATE TABLE contacts (
  id INT AUTO_INCREMENT PRIMARY KEY,

  email VARCHAR(100),
  phone VARCHAR(20)
);

💻 STEP 2: Create PHP Files

📄 db.php – Database Connection

<?php
$host = 'localhost';
$user = 'root';
$password = ''; // Change if needed
$database = 'contact_book';

$conn = new mysqli($host, $user, $password, $database);

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

        </tr>
        <?php
        $result = $conn->query("SELECT * FROM contacts");
        while ($row = $result->fetch_assoc()) {
            echo "<tr>
