How can PHP frameworks like Symfony2 be leveraged to improve the overall security and structure of a web application?

Using PHP frameworks like Symfony2 can improve the overall security and structure of a web application by providing built-in security features such as CSRF protection, input validation, and user authentication. These frameworks also follow best practices for organizing code, making it easier to maintain and update the application. 

// Example of using Symfony2's CSRF protection in a form
$form = $this->createFormBuilder()
    ->add('name', TextType::class)
    ->add('email', EmailType::class)
    ->add('submit', SubmitType::class)
    ->getForm();

$form->handleRequest($request);

if ($form->isSubmitted() && $form->isValid()) {
    // Process form data
}
