Define variables outside the PHP class
I m using zend.
I want to define the below code outside the controller class & access in different Actions.
$user = new Zend_Session_Namespace('user');
$logInArray = array();
$logInArray['userId'] = $user->userid;
$logInArray['orgId'] = $user->authOrgId;
class VerifierController extends Syste开发者_开发百科madminController
{
public function indexAction()
{
// action body
print_r($logInArray);
}
}
But it does not print this array in index function on the other hand it show this array outside the class.
How it is possible. Thanks.
To access a global variable from inside a method/function, you have to declare it as global
, inside the method/function :
class VerifierController extends SystemadminController
{
public function indexAction()
{
global $logInArray;
// action body
print_r($logInArray);
}
}
In the manual, see the section about Variable scope.
Still, note that using global variables is not quite a good practice : in this case, your class is not independant anymore : it relies on the presence, and correct definition, of an external variable -- which is bad.
Maybe a solution would be to :
- pass that variable as a parameter to the method ?
- or pass it to the constructor of your class, and store it in a property ?
- or add a method that will receive that variable, and store it in a property, if you cannot change the constructor ?
print_r($GLOBALS['logInArray']);

You can store the user in many ways and access it in more clean manner. You can store it in Zend_Registry and then use Zend_Registry::get('user') where you need to retrieve the user. You can also store it as a parameter of request object, and then in a controller simply do $user = $this->_getParam('user');
If you need access to the user array in many controllers that inherit from the SystemadminController, what you can do is store it as a protected property of the SystemadminController (eg. protected $_user). Then all you need to do in child controllers is access $this->_user.
