What are some best practices for securely updating news content online using PHP?

When updating news content online using PHP, it is important to ensure that the process is secure to prevent unauthorized access or malicious content injection. One best practice is to use prepared statements with parameterized queries to prevent SQL injection attacks. Additionally, validating and sanitizing user input before updating the database can help prevent cross-site scripting (XSS) attacks. 

// Sample code for securely updating news content online using PHP

// Establish database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "news_db";

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

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

// Validate and sanitize user input
$title = mysqli_real_escape_string($conn, $_POST['title']);
$content = mysqli_real_escape_string($conn, $_POST['content']);

// Prepare SQL statement with parameterized query
$stmt = $conn->prepare("UPDATE news SET title = ?, content = ? WHERE id = ?");
$stmt->bind_param("ssi", $title, $content, $_POST['id']);

// Execute the statement
$stmt->execute();

// Close statement and connection
$stmt->close();
$conn->close();
