Are there any security considerations to keep in mind when developing a PHP forum?

When developing a PHP forum, it is important to consider security measures to protect user data and prevent unauthorized access. One key consideration is to sanitize user input to prevent SQL injection attacks. Additionally, implementing proper authentication and authorization mechanisms, such as using secure password hashing and session management, can help secure the forum against unauthorized access. 

// Sanitize user input to prevent SQL injection
$username = mysqli_real_escape_string($conn, $_POST['username']);
$password = mysqli_real_escape_string($conn, $_POST['password']);

// Secure password hashing
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Session management for authentication
session_start();
$_SESSION['logged_in'] = true;
