Set and get global variable in php (ZendFramework)

Question

I am using ZendFramework with PHP, and I want to set and get a variable as a global variable. I.E. I set it in the class of Zend Controller and access it any action in the class.

For example:

<?php

class SubscriptionController extends Zend_Controller_Action
{
    private $EMAIL = false;
    private $USERNAME = false;

First I am validating email addres with ajax call

    public function checkusernameAction()
    {
        $email = //query to find email;     
        if($email){
        $EMAIL = true;
        }else{
        $EMAIL = false;
        }
    }

then I want subscribe user on the basis of private variable again with ajax call

    public function subscribeAction
    {
      if($EMAIL == true)
       {
         //some stuff 
       }        
    }

I am getting private var by $this->EMAIL, but not able to access it

Solution

You can use Zend_Registry to use the variable throughout application.

You can set a variable like this

Zend_Registry::set('email', $EMAIL);

and later can get it like this

$email= Zend_Registry::get('email');

Thanx buddy.... this is the good option but I am facing a problem i.e I initialize the registry in init() with ::set('email' false) and again declaring it in other action that I am calling with ajax as ::set('email', true), and then checking it in third function as true or false and everytime i am getting false. Is there any other option to do the same

I'm not sure if it will ease your life or not, but you could pass round a config object in the registry which just handles a subset of configuration options?

This is to access variable inside a class..But I want to access variable from different controllers and models.Like a catalyst object in catalyst framework

The link you mentioned about Zend_Registry is not working
