New Comment:
I have reproducted this problem... and am pretty sure what is exactly
is going wrong...
<?
class foo
{
function foo()
{
$this->bar = new bar();
}
}
class bar
{
function bar()
{
$this->tmp = "bar";
}
function do_nothing()
{
}
}
$foo = new foo();
$foo->bar->tmp = "test";
$foo2 = $foo;
$foo2->bar->tmp = "foo";
var_dump($foo);
var_dump($foo2);
// now....
$foo->bar->do_nothing();
$foo3 = $foo;
$foo3->bar->tmp = "bug";
var_dump($foo);
var_dump($foo3);
?>
Basically when you call a method from a objects member object. It
creates that member as a refrence.
/* i set this to critical because i think this should be resloved right
away */

I'm looking at putting php 4.1.1 into the next RH release
however I noticed that this bug still seems to be happening
(From make test)
Running tests in /usr/src/redhat/php-4.1.1//tests/lang
...
OO Bug Test (Bug #7515) (029.phpt) ... failed
[root@dhcpd201 lang]# cat 029.exp
success
[root@dhcpd201 lang]# cat 029.out
failure
I this something that can either be fixed or can I turn a
blind eye to this..

Is this still a issue? This report is updated a year ago...
If this report is outstanding, PHP Version is better to be updated...

assigned to zeev, as discussed we either need
a) a permanent fix
b) a permanent deep copy function and understand this effect
as a feature and users will eventually have to use deep
copies for some containers

This code is pretty self-explanatory...
Uncommenting the noticed (*[0]) line, causes the object contained
('root') in the instance of 'obj' to be referenced to whatever,
function test() uses a copy $o_copy but reference-counting fails and
the contained object 'root' is somehow referenced to the original
object in the global scope.
After having uncommented *[0] try to uncomment *[1] what should break
the reference again, that made me assuming this all is caused by
reference counting...
<?php
class obj {
function method() {}
}
function test($o_copy) {
//$o_copy->root=&$o_copy->root; // *[1]
$o_copy->root->set_in_copied_o=TRUE;
var_dump($o_copy);?><BR><?php }
$o->root=new obj();
//$o->root->method(); // *[0] uncomment this line and weirdness starts
var_dump($o);?><BR><?php
test($o);
var_dump($o);
?>
