Are there any specific PHP functions or libraries that are recommended for fetching and displaying data from a website in a secure and efficient manner?

When fetching and displaying data from a website in PHP, it is important to use secure and efficient methods to prevent vulnerabilities such as SQL injection or cross-site scripting attacks. One recommended approach is to use prepared statements when interacting with a database to prevent SQL injection. Additionally, using PHP libraries like cURL can help securely fetch data from external websites. 

// Example using prepared statements to fetch data from a database securely
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// Prepare and execute a statement
$stmt = $conn->prepare("SELECT id, name FROM users WHERE id = ?");
$stmt->bind_param("i", $id);

$id = 1;
$stmt->execute();

$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
    echo "id: " . $row["id"] . " - Name: " . $row["name"] . "<br>";
}

$stmt->close();
$conn->close();
