快速入門

創建一個用戶

Sentry::register(array(
    'email'    => 'john.doe@example.com',
    'password' => 'foobar',
));

驗證一個用戶

Sentry::authenticate(array(
    'email'    => 'john.doe@example.com',
    'password' => 'foobar',
));

創建一個分組

Sentry::createGroup(array(
    'name'        => 'Subscribers',
    'permissions' => array(
        'admin' => 1,
        'users' => 1,
    ),
