Question

I have a PHP class like the following

<?php
class Test{
  var $conf = array('a' => 1, 'b' => 2, c => 3);

  private function do_something(){
    // Do something Here
    function do_something_else(){
      // How to get the variable value for $conf ???? o.O
    }
  }
}
?>

I want to access $conf inside the function do_something_else(). In the upper level functions I am able to access this as $this->conf, but I guess $this would not be available in the inner function. What would be the best possible way to access the variables inside that function?

I cannot pass the values as this function would be called by a built-in function in WordPress CMS, so passing arguments can not be a choice here.

I believe what you need is anonymous function, here is some solutions.
You can do in PHP 5.3:

 class Test{
    var $conf = array('a' => 1, 'b' => 2, 'c' => 3);

    private function do_something(){
        // Do something Here
        $that = $this;
        $do_something_else = function() use($that) {
            echo $that->conf;
        };

        $do_something_else();   
    }
}

Or use $this directly on anonymous function but only PHP 5.4.
