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:
----------------------------
tclass Object
(
    [tProperty] => tclass Object
        (
            [tProperty] =>  *RECURSION*
            [name] => Sam
        )

    [name] => Sam
)
tclass Object
(
    [tProperty] => tclass Object
        (
            [tProperty] =>  *RECURSION*
            [name] => George
        )

    [name] => George
)


----------------------------
Instead of:
----------------------------
tclass Object
(
    [tProperty] => *RECURSION*
    [name] => Sam
)
tclass Object
(
    [tProperty] => *RECURSION*
    [name] => George
)

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The 1st instance of recursion is always shown. Consider print_r($GLOBALS);
