Access Class Variable inside another class

[eluser]adamp1[/eluser]
I have the following setup

Code:

class Page extends Controller
{
  function Page()
  {
    $this->_variable = "something";
  }

  function index()
  {
    $this->Library->method();
  {
}

class Library
{
  function method()
  {
    // Use $_variable
  }
}

So is there a way the library can access the variable without it being passed explicitly to the class/method?

[eluser]Negligence[/eluser]
Create a get() method to retrieve the variable, and pass $this (the controller object) to the Library when you create it. Then just call $controllerObj->getVar() from within the library.

Option 1) Library extends Page
Option 2) Instantiate Page inside of Library and access the member variable like $page->_variable or using a get() method

You can also make the property static:

Code:

class Page extends Controller
{
  static $_variable;
  function Page()
  {
    $this->_variable = "something";
  }

  function index()
  {
    $this->Library->method();
  {
}

class Library
{
  function method()
  {
    // Use $_variable
    echo Page::$_variable;
  }
}

If Page is the current controller you can

Code:

$CI =& get_instance()
$CI->_variable
