New Comment:
I have tested on window with apache 2.2.6 the snap.zip you given.
The bug is still there.
A & for reference is still leaved after call array_walk_recursive on
val2 and original array can't be duplicate anymore after.
Reproduce code:
--------------
echo PHP_VERSION;
$data = array ('key1' => 'val1', array('key2' => 'val2'));
echo '<pre>';
function foo2($item, $key) {}; // dumb callback function
var_dump($data);
array_walk_recursive($data, 'foo2');
$data2 = $data; // Duplicate array
$data2[0] = 'altered'; // Alter copy
var_dump($data);
var_dump($data2);
Expected result:
----------------
5.3.0-dev
array(2) {
["key1"]=>
string(4) "val1"
[0]=>
array(1) {
["key2"]=>
string(4) "val2"
}
}
array(2) {
["key1"]=>
string(4) "val1"
[0]=>
string(7) "val2"
}
array(2) {
["key1"]=>
string(4) "val1"
[0]=>
string(7) "altered"
}
Actual result:
--------------
5.3.0-dev
array(2) {
["key1"]=>
string(4) "val1"
[0]=>
array(1) {
["key2"]=>
string(4) "val2"
}
}
array(2) {
["key1"]=>
string(4) "val1"
[0]=>
&string(7) "altered"
}
array(2) {
["key1"]=>
string(4) "val1"
[0]=>
&string(7) "altered"
}

Description:
------------
I have to reopen this bug http://bugs.php.net/bug.php?id=42655 because
it was incorrectly closed and tony2001 doesn't seem to receive email.
Here Copy/paste email i send him.
This is not the same bug.
In #34982, an array is modified outside the function func() that call
array_walk_recursive. This bug doesn't exist anymore in 5.2.4
The bug i report is when calling array_walk_recursive on an array
(callback function doesn't even have reference & for array input and
does nothing).
Original array shouldn't be modified, but if you var_dump it, you can
see reference on subarray
[0]=> &array(1)
instead of
[0]=> array(1)
The array shouldn't have been modified but array_walk_recursive leaves
references.
This can cause trouble, eg you cant duplicate the original array
anymore. Look at following example
$data = array ('key1' => 'val1', array('key2' => 'val2'));
function foo($item, $key) {}; // dumb callback function
var_dump($data);
array_walk_recursive($data, 'foo');
$data2 = $data; // Duplicate array
$data2[0] = 'altered'; // Alter copy
var_dump($data);
var_dump($data2);
array(2) {
["key1"]=> string(4) "val1"
[0]=> &string(5) "bingo"
}
array(2) {
["key1"]=> string(4) "val1"
[0]=> &string(5) "bingo"
}
both $data and $data2 are altered;
Reproduce code:
---------------
$data = array ('key1' => 'val1', array('key2' => 'val2'));
function dumb($i, $k){}
var_dump($data);
array_walk_recursive($data,'foo');
// Double check the [0]=>&array(1) in actual result
var_dump($data);
Expected result:
----------------
Expected result:

array(2) {
["key1"]=> string(4) "val1"

["key1"]=> string(4) "val1"
[0]=> array(1) {
["key2"]=> string(4) "val2"
}
}
