To implement PHP password Hashing on a login page, follow these steps:
$password = passwordhash($inputPassword, PASSWORDDEFAULT);
Retrieve username and password from login form When the user submits the login form, retrieve the entered username and password from the form through the POST method.
Verify the entered password To verify the entered password, retrieve the hashed password associated with the entered username from the user database. Use the password_verify() function to verify the entered password against the hashed password retrieved from the database.
For example:
$user = getUser($username); // retrieve user information from database if ($user && passwordverify($inputPassword, $user['password'])) { // Login successful: set session variable and redirect to dashboard $SESSION['username'] = $username; header('Location: dashboard.php'); exit; } else { // Login failed: display error message $errorMessage = 'Invalid username or password'; }
That's it! You have now implemented PHP password hashing on a login page.
