$username = $_POST['username']; $password = $_POST['password']; $user = User::whereUsername($username); if ($user && password_verify($password, $user->password)) { // Log in successful } else { // Invalid username or password }
$username = $_POST['username']; if (User::whereUsername($username)) { // Username already exists } else { // Username is available }This code snippet is used when a user creates a new account. It checks if the username they entered already exists in the database using the whereUsername function. If so, it lets the user know that the username is already taken. Package library: This app likely uses a PHP package library to handle database interactions, such as Eloquent ORM.
