how to access paratmeter passed in request

how to access this paramvalue in controller..?

$router->map('Company', 'Company', array( 
 'controller' => 'companies', 
 'action' => 'add', 
 'paramkey' => 'paramvalue', 
 'anotherparam' => 'anotherv开发者_如何学编程alue')); 

Plz help me

Try

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

get one param:

$this->getRequest()->getParam('paramkey'[, 'default value']);

get all params:

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

or

$this->_getParam('paramkey'[, 'default value']);
$this->_getAllParams();

I`m using Zend Framework so method described in Zend_Action_Contoller:

/**
 * Gets a parameter from the {@link $_request Request object}.  If the
 * parameter does not exist, NULL will be returned.
 *
 * If the parameter does not exist and $default is set, then
 * $default will be returned instead of NULL.
 *
 * @param string $paramName
 * @param mixed $default
 * @return mixed
 */
protected function _getParam($paramName, $default = null)

if you are using CacePHP you can try

$this->params['paramkey'];

but I`m not sure it will work
