  * You can also pass the URL as an array:
  *
  * ```
  * $vars = $this->requestAction(['controller' => 'articles', 'action' => 'popular']);
  * ```
  *
  * ### Passing other request data
  *
  * You can pass POST, GET, COOKIE and other data into the request using the appropriate keys.
  * Cookies can be passed using the `cookies` key. Get parameters can be set with `query` and post
  * data can be sent using the `post` key.
  *
  * ```
  * $vars = $this->requestAction('/articles/popular', [
  *   'query' => ['page' => 1],
  *   'cookies' => ['remember_me' => 1],
  * ]);
  * ```
  *
  * ### Sending environment or header values
  *
  * By default actions dispatched with this method will use the global $_SERVER and $_ENV
  * values. If you want to override those values for a request action, you can specify the values:
  *
  * ```
  * $vars = $this->requestAction('/articles/popular', [
  *   'environment' => ['CONTENT_TYPE' => 'application/json']
  * ]);
  * ```
  *
  * ### Transmitting the session
  *
  * By default actions dispatched with this method will use the standard session object.
  * If you want a particular session instance to be used, you need to specify it.
  *
  * ```
  * $vars = $this->requestAction('/articles/popular', [
  *   'session' => new Session($someSessionConfig)
  * ]);
  * ```
  *
  * @param string|array $url String or array-based url.  Unlike other url arrays in CakePHP, this
  *    url will not automatically handle passed arguments in the $url parameter.
  * @param array $extra if array includes the key "return" it sets the autoRender to true.  Can
  *    also be used to submit GET/POST data, and passed arguments.
  * @return mixed Boolean true or false on success/failure, or contents
  *    of rendered action if 'return' is set in $extra.

 /**
  * Calls a controller's method from any location. Can be used to connect controllers together
  * or tie plugins into a main application. requestAction can be used to return rendered views
  * or fetch the return value from controller actions.
  *
  * Under the hood this method uses Router::reverse() to convert the $url parameter into a string
  * URL. You should use URL formats that are compatible with Router::reverse()
  *
  * ### Examples
  *
  * A basic example getting the return value of the controller action:
  *
  * {{{
  * $variables = $this->requestAction('/articles/popular');
  * }}}
  *
  * A basic example of request action to fetch a rendered page without the layout.
  *
  * {{{
  * $viewHtml = $this->requestAction('/articles/popular', ['return']);
  * }}}
  *
  * You can also pass the URL as an array:
  *
  * {{{
  * $vars = $this->requestAction(['controller' => 'articles', 'action' => 'popular']);
  * }}}
  *
  * ### Passing other request data
  *
  * You can pass POST, GET, COOKIE and other data into the request using the apporpriate keys.
  * Cookies can be passed using the `cookies` key. Get parameters can be set with `query` and post
  * data can be sent using the `post` key.
  *
  * {{{
  * $vars = $this->requestAction('/articles/popular', [
  *   'query' => ['page' = > 1],
  *   'cookies' => ['remember_me' => 1],
  * ]);
  * }}}
  *
  * @param string|array $url String or array-based url.  Unlike other url arrays in CakePHP, this
  *    url will not automatically handle passed arguments in the $url parameter.
  * @param array $extra if array includes the key "return" it sets the autoRender to true.  Can
  *    also be used to submit GET/POST data, and passed arguments.
  * @return mixed Boolean true or false on success/failure, or contents
  *    of rendered action if 'return' is set in $extra.
