What are the best practices for comparing user input passwords with stored passwords in PHP?

When comparing user input passwords with stored passwords in PHP, it is essential to use a secure hashing algorithm like bcrypt to store passwords securely. When a user logs in, you should hash the input password and compare it with the hashed password stored in the database. This way, even if the database is compromised, the passwords remain secure. 

// Hashing the user input password
$user_input_password = $_POST['password'];
$hashed_user_input_password = password_hash($user_input_password, PASSWORD_BCRYPT);

// Comparing hashed user input password with stored hashed password
$stored_password = "hashed_password_from_database";
if (password_verify($user_input_password, $stored_password)) {
    // Passwords match
    echo "Passwords match!";
} else {
    // Passwords do not match
    echo "Passwords do not match!";
}
