I don't agree with this. The zend engine only does a shallow copy in this particular
instance, and it is a bug. If the array is not accessed through a method in the
object, the copy is performed correctly. Please re-analyze this.

Zend copies arrays and objects "shallow" (for performance
reasons). The workaround is to implement "clone" method.
This probably should be built-in function in Zend.

The workaround that I have had to implement is doing an explicit clone method (similar
to a copy constructor) and when making a copy, say
$new = $old->clone();
instead of
$new = $old;
example implementation:
class Element
{
var $value;
function &clone()
{
$obj = new Element();
$obj=>value = $this->value;
}
}
class X
{
var $array;
function &clone()
{
$obj = new X();
foreach($this->array as $index => $value)
{
$obj->array[$index] = $value->clone();
}
return $obj;
}
}
