im re-factoring php on zend code and all the code is full of $_GET[\"this\"] and $_POST[\"that\"]. I have always used the more phpish $this->_
$_GET[\"this\"]
$_POST[\"that\"]
$this->_
not directly related to the topic, but to insure that you get an number in your input, one could also use $var+0 (however if $var is a float it stays a float) you may use in most cases $id = $this->_request->getQuery('id')+0;
