Running the code below shows that $cls->tProperty is _NOT_ the same variable as the object itself. However, it should be. It lies that $cls->tProperty is another instance of tClass class. Despite of this, when one changes the name property, it will result in change in both objects, and that's correct.


class tClass {
	var $tProperty;
	var $name;
	function tClass() {
		$this->tProperty =& $this;
	}
};

echo "<pre>";
$cls =& new tClass();
$cls->name = "Sam";
print_r($cls);
$cls->name = "George";
print_r($cls);
echo "</pre>";

/*

Output:

    [tProperty] => tclass Object

        )

    [name] => George

Instead of:

tclass Object
