How can PHP and MySQL be effectively integrated to ensure accurate and efficient data retrieval and display on a website?

To effectively integrate PHP and MySQL for accurate and efficient data retrieval and display on a website, you can use PHP's MySQLi extension or PDO (PHP Data Objects) for database connectivity. These provide secure and efficient ways to interact with a MySQL database and retrieve data to display on a website. 

// Example using MySQLi extension
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Query to retrieve data from MySQL database
$sql = "SELECT id, name, email FROM users";
$result = $conn->query($sql);

// Display retrieved data on the website
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. " - Email: " . $row["email"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
