This helper function gives you friendlier syntax to get browser cookies. Refer to the Input Library for detailed description of its use, as this function acts very similarly to CI_Input::cookie(), except it will also prepend the $config['cookie_prefix'] that you might’ve set in your application/config/config.php file.

Parameters:
  • $name (string) – Cookie name
  • $domain (string) – Cookie domain (usually: .yourdomain.com)
  • $path (string) – Cookie path
  • $prefix (string) – Cookie name prefix
Return type:

void

Lets you delete a cookie. Unless you’ve set a custom path or other values, only the name of the cookie is needed.

delete_cookie('name');

This function is otherwise identical to set_cookie(), except that it does not have the value and expiration parameters. You can submit an array of values in the first parameter or you can set discrete parameters.

delete_cookie($name, $domain, $path, $prefix);
