Question

In Zend Framework, most of the time to get a param, i will use

// from controller
$this->getRequest()->getParam('key');

but how can i get just GET params using the ‘Zend’ way? Or do i just use $_GET? Is there any difference between

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

vs

$_GET['key'];

Answer 1

Use getQuery():

$this->_request->getQuery('key');

Other methods available include

• getParam()
• getQuery()
• getPost()
• getCookie()
• getServer()
• getEnv()

getParam() checks user params first, then $_GET, and then $_POST, returning the first match found or null.

Try to avoid accessing the superglobals directly.
