Description:
------------
A declared variable in a class can't be set to NULL or unset

Test script:
---------------
class myClass {
	private $var = null;

	function __construct() {
		$this->var = "Hello";
	}

	public function func()
	{
		$this->var = null;  // Does nothing, still "Hello"
		unset($this->var);  // Does nothing, still "Hello"
		$this->var = false; // Works
	}
}

Expected result:
----------------
Variable should be null

Actual result:
--------------
Variable stays as "Hello"
