Question

I have a base controller that log errors and I want include in the log message ALL request data, ALL headers and request body. How can I do that in CodeIgniter?

Answer 1

CodeIgniter $this->input which is equivalent to file_get_contents('php://input') contains all the Body request (if any) an output from foo var_dump($this->input) would look like:

object(CI_Input)[9]
  public 'ip_address' => boolean false
  public 'user_agent' => boolean false
  public '_allow_get_array' => boolean true
  public '_standardize_newlines' => boolean true
  public '_enable_xss' => boolean false
  public '_enable_csrf' => boolean false
  protected 'headers' => 
    array (size=0)
      empty
  public 'security' => &
    object(CI_Security)[8]
      protected '_xss_hash' => string '' (length=0)
      protected '_csrf_hash' => string '' (length=0)
      protected '_csrf_expire' => int 7200
      protected '_csrf_token_name' => string 'ci_csrf_token' (length=13)
      protected '_csrf_cookie_name' => string 'ci_csrf_token' (length=13)
      protected '_never_allowed_str' => 
        array (size=10)
          'document.cookie' => string '[removed]' (length=9)
          'document.write' => string '[removed]' (length=9)
          '.parentNode' => string '[removed]' (length=9)
          '.innerHTML' => string '[removed]' (length=9)
          'window.location' => string '[removed]' (length=9)
          '-moz-bindin.......//and many other data.

and for the headers laso you have the new command in PHP 5.4 which is headers_list(). and also, many other data can be contained in the CI seesion like: ip_address, user_agent ,last_activity
