Description:
------------
In the following code __clone() have problems with member variables of
type
object ($this->obj is null). If the comment is removed from the call
to
__clone2() in __clone() then __clone2() also has problems with the
vision. On
the other hand __clone2() has no problems when called externally. The
difference between the expected and the actual result is the second
call to print_r()
Reproduce code:
---------------
<?php
class clone_example {
private $pub = 2;
private $obj = NULL;
function clone_example($obj) {
$this->obj = $obj;
}
function __clone() {
print_r($this);
// $this->__clone2();
}
function __clone2() {
print_r($this);
}
}
class fubar {
public $v = array(1,2,3);
}
$fu = new fubar();
$a = new clone_example($fu);
$a->__clone2();
$a->__clone();
$a->__clone2();
?>
Expected result:
----------------
clone_example Object
(
[pub:private] => 2
[obj:private] => fubar Object
(
[v] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
)
clone_example Object
(
[pub:private] => 2
[obj:private] => fubar Object
(
[v] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
)
clone_example Object
(
[pub:private] => 2
[obj:private] => fubar Object
(
[v] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
)
Actual result:
--------------
clone_example Object
(
[pub:private] => 2
[obj:private] => fubar Object
(
[v] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
)
clone_example Object
(
[pub:private] => 2
[obj:private] =>
)
clone_example Object
(
[pub:private] => 2
[obj:private] => fubar Object
(
[v] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
)
