If you're within an action controller, yes, there's an easy way:
if ($this->_hasParam($name)) {
// found!
}
Another easy way is to pass the second parameter to getParam(), which is
used for providing a default value; you can then test for the default
value:
if (!$request->getParam('foo', false)) {
// not found
}
This latter is somewhat problematic, as you could potentially have a
false value passed. On the other hand, a null value can never be passed,
and you can test for that:
if (null === $request->getParam('foo')) {
// not found
}
