Are there any recommended best practices for securing a PHP login system to prevent unauthorized access?

To secure a PHP login system and prevent unauthorized access, it is recommended to use secure password hashing techniques, implement measures to prevent brute force attacks, and ensure proper session management to protect against session hijacking.

// Use password_hash() function to securely hash passwords
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Implement measures to prevent brute force attacks
// For example, limit the number of login attempts within a certain timeframe

// Use session_regenerate_id() to regenerate session ID to prevent session hijacking
session_regenerate_id();
