Zend Framework $ _REQUEST相当于

I need to capture several parameters in a controller regardless of whether the were posted or they are in the url.

Does $this->_request->getParam('parameter') work regardless?

To make life easier and shorter code, you can use the _getParam function in your controllers:

$page = $this->_getParam('page', 1);

Note that the second function variable is the default value if the request didn't include that specific variable.

Short answer, yes.

If you are in the controller, you can access any POST of GET parameter by accessing the getParam() method like you said.

$this->getRequest()->getParam("foo") will get the parameter foo, if it is present in the URL via a get param, or in a POST. It will also get any user set parameters.

The

$this->getRequest()->getParams();

Will get several parameters regardless of the action type being sent (get or post).

$this->getRequest()->getParam('foo');

Will get you individual requested parameter.

i prefer always use short function:

$parameter = $this->_getParam('parameter');
