How can PHP beginners effectively implement password hashing in their login systems to enhance security and protect user data?

To enhance security and protect user data in a PHP login system, beginners can implement password hashing. This involves securely hashing user passwords before storing them in the database, making it difficult for attackers to access plaintext passwords even if the database is compromised. 

// Hashing user password before storing it in the database
$password = $_POST['password']; 
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Verifying hashed password during login
$entered_password = $_POST['password']; 
$stored_hashed_password = // Retrieve hashed password from the database based on user input

if (password_verify($entered_password, $stored_hashed_password)) {
    // Password is correct
    // Proceed with login process
} else {
    // Password is incorrect
    // Display error message
}
