I've just made use of overloaded property access for the first time and
experienced some unexpected behavior.  I just wanted to verify that it was
the correct behavior with those who'd know best.

<?php

class One {
	public function __construct() {
		$this->two = new Two();
	}
	
	public function __set( $n, $v ) {
		$GLOBALS[$n] = $v;
	}
	
	public function __get( $n ) {
		return $GLOBALS[$n];
	}
}

class Two {
	public $property = "default value";	
}

$one = new One();

print( "\"" . $one->two->property . "\"n" );

$one->two->property = "new value";

?>

This produces:
=================
$ php -f test.php
"default value"
PHP Fatal error:  Cannot access undefined property for object with
overloaded property access in /home/fletch/test.php on line 24
=================

Is it correct that $one->two->property should be read only?

Thanks.

After sending this mail I went and searched the bugs database more
thoroughly and found this very problem here:
http://bugs.php.net/bug.php?id=28444.

My apologies.
