What are some recommended resources or tutorials for implementing secure user authentication and access control in PHP web development?

Secure user authentication and access control are crucial aspects of web development to protect user data and prevent unauthorized access to sensitive information. To implement secure user authentication in PHP, developers can utilize password hashing functions like password_hash() and password_verify() to securely store and verify user passwords. Access control can be implemented by using sessions and role-based permissions to restrict access to certain pages or functions based on the user's role.

// Example of secure user authentication in PHP using password_hash() and password_verify()

// Register a new user
$password = 'password123';
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Store $hashed_password in the database

// Verify user login
$entered_password = 'password123';

if (password_verify($entered_password, $hashed_password)) {
    // User authentication successful
} else {
    // User authentication failed
}
