What are the best practices for ensuring secure user authentication in PHP-based Content Management Systems?

To ensure secure user authentication in PHP-based Content Management Systems, it is important to use strong password hashing algorithms, implement secure session management, and protect against common vulnerabilities such as SQL injection and cross-site scripting attacks. 

// Example of secure user authentication in PHP

// Step 1: Hash the user's password using a strong hashing algorithm like bcrypt
$password = 'user_password';
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Step 2: Store the hashed password in the database
// Example SQL query: INSERT INTO users (username, password) VALUES ('user', '$hashed_password');

// Step 3: Verify the user's password during login
$entered_password = 'user_password';
$stored_hashed_password = 'retrieved_hashed_password_from_database';

if (password_verify($entered_password, $stored_hashed_password)) {
    echo 'Password is correct. User authenticated.';
} else {
    echo 'Password is incorrect. User authentication failed.';
}
