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.

Hello,
most probably that property is a reference in which case the result is
correct.

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
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();

That should be clone $object for the example.

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)#1 (1)
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.

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;
$clone-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);
