What are the best practices for handling password protection in PHP to ensure security?

To ensure password protection in PHP, it is best practice to use a secure hashing algorithm like bcrypt to securely store passwords. This helps protect user passwords in case of a data breach. Additionally, it is important to validate user input and use prepared statements to prevent SQL injection attacks. 

// Hashing password using bcrypt
$password = 'password123';
$hashedPassword = password_hash($password, PASSWORD_BCRYPT);

// Verifying password
$enteredPassword = 'password123';
if (password_verify($enteredPassword, $hashedPassword)) {
    echo 'Password is correct';
} else {
    echo 'Password is incorrect';
}
