How should the password_verify() function be used in the PHP login script?

When using the password_verify() function in a PHP login script, you should compare the hashed password stored in the database with the password entered by the user. This function verifies if the entered password matches the hashed password securely. You should retrieve the hashed password from the database based on the user's input (such as email or username) and then use password_verify() to check if the entered password is correct.

// Retrieve hashed password from the database based on user input (e.g., email or username)
// Assuming $storedPassword contains the hashed password retrieved from the database

$userInputPassword = $_POST['password']; // Get the password entered by the user

if (password_verify($userInputPassword, $storedPassword)) {
    // Password is correct, proceed with login
    // Add your login logic here
} else {
    // Password is incorrect, display an error message
    echo "Incorrect password. Please try again.";
}
