i found several ways get parameters inside controller > action in zend framework 2 : $this->params()->fromroute('id'); $this->params('id'); $this->getrequest()->getquery()->get('id'); is there difference among these ways? i guess, params('id') may give values get , post both. fromroute , getquery give value get only, fromroute may give advantages sanitation or something? $this->params()->fromroute('id'); this uses params plugin , returns single named route parameter. used parameters in segment routes (e.g. 'slug' /blog/:slug or 'year' /archive/:year/:month/:day ). $this->params('id'); this shorthand $this->params()->fromroute('id'); . $this->getrequest()->getquery()->get('id'); this grabs value query string.
