Can anyone link me to some Symfony resources, they are hard to find. I am having a little trouble understanding how to use it correctly. Like with CodeIgniter to use the security helper you would load it doing this:
$this->load->helper('security');
And you would use its functions you would do something like this:
$data = $this->input->xss_clean($data);
But with Smyfony to redirect someone to a 404 page, you need to use the sfAction class and the redirect404() api. So could anyone explain or link me a good tutorial?
