This was never resolved:
Is this, or is this not a bug:
class A
{
var $a;
}
$A = new A;
$A->a = array(1);
$array = &$A->a;
$clone = clone $A;
$clone->a = array(); //Affects a in $A.
print_r($A);

This too:
class A
{
var $a = array();
public function &getA()
{
return $this->a;
}
}
$A = new A;
$A->a = array(1);
$array = &$A->getA();
$clone = clone $A;
$clone->a = array();
print_r($A);

Here, I have reproduced the problem:
class A
{
var $a = array();
public function makeAReference()
{
$array = $this->getA();
}
public function &getA()
{
return $this->a;
}
}
$A = new A;
$A->a = array(1);
$A->makeAReference();
$clone = clone $A;

first as i said do the following to verify:
It's a nice example, but it doesn't apply. I don't make a reference.
second read the docs and question such things on [EMAIL PROTECTED]
I did. This problem seemed to be internal, and it still does.

Hello,
first as i said do the following to verify:
[EMAIL PROTECTED] /usr/src/php5 $ php -r '$a=array(1,2);class t{public $a;function
f(){$this->a=&$GLOBALS["a"];}}$o1=new t;$o1->f();var_dump($o1);$o2=clone
$o1;$o1->a=2;var_dump($o2);var_dump($o1);'
make: `sapi/cli/php' is up to date.
object(t)#
That should be clone $object for the example.

More specifically,
This causes a change in $object:
$clone = clone $object;
$clone->troublesomeVariable = array();
But this doesn't:
$clone = clone $cell;
$clone = null;
$clone->_subElements = array();

It appears that only one of the variables, an array, is being shared
across these multiple objects, but other array variables are not.
Moreover, When I make a clone and then set the clone to null, all
clones made thereafter are correct.
$clone = clone $object;
$clone = null;
Also, I can't repli
Hello,
most probably that property is a reference in which case the result is
correct.

It appears that cloning is broken, since a modification to the clone
modifies the original. For my __clone method implementation, I allow
all of the variables to be set by default except for one. But this
problem persists even when I don't modify that one variable.
