What are the differences between the security features of Laravel and CodeIgniter?

In security feature comparison: CSRF protection: Laravel is enabled by default, CodeIgniter needs to be enabled manually. XSS protection: Built-in in Laravel, provided by CodeIgniter but needs to be applied manually. Input validation: Laravel has built-in validators and CodeIgniter provides input filters. Database security: Laravel uses Eloquent ORM and CodeIgniter uses Active Record ORM. Session management: Laravel encrypts and garbage collects by default, CodeIgniter requires manual configuration.

Comparison of security features between Laravel and CodeIgniter

Introduction:
Laravel and CodeIgniter are both popular PHP frameworks. Security is an important consideration when choosing a framework. Let’s understand the difference between Laravel and CodeIgniter in terms of security features.

CSRF protection:

• Laravel: CSRF protection is enabled by default and is verified by token.
• CodeIgniter: CSRF protection must be manually enabled, authenticated via XSS filtering.

XSS Protection:

• Laravel: Built-in XSS filtering and automatic escaping in responses.
• CodeIgniter: Provides XSS filtering capabilities, but must be applied manually.

Input validation:

• Laravel: Provides built-in validators that use rules and messages for validation.
• CodeIgniter: Provides input filters for cleaning and validating input.

Database Security:

• Laravel: Provides built-in query binding using Eloquent ORM to prevent SQL injection.
• CodeIgniter: Provides Active Record ORM, which does not perform query binding by default.

Session Management:

• Laravel: Uses the session driver, providing encryption and garbage collection.
• CodeIgniter: Provides a session manager, but encryption and garbage collection require manual configuration.

Practical case:

Laravel CSRF protection:

class ExampleController extends Controller
{
    public function index()
    {
        return view('index', [
            '_token' => csrf_token()
        ]);
    }
}

CodeIgniter CSRF protection:

$this->load->helper('form');
echo form_open('myform', ['csrf' => TRUE]);
?>

**Laravel XSS 保护：**

{{ $text | e }}

**CodeIgniter XSS 保护：**

$this->security->xss_clean($text);
