New Comment:
This bug has been fixed in CVS.
In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.

They're actually mangled with CVS HEAD too..somehow I missed that or
had those print_r() lines in wrong place. :I

In 4.3.2 the source arrays are mangled even when you don't add them to
the result.
This was just for a nicer, smaller example.
Example
========
// Same $a and $b as before
$result = array_merge_recursive( $a, $b );
print_r( $c );
print_r( $a );
print_r( $b );
// have sadly the same effect

Reproduced using latest CVS. The original arrays are fine, but when
they're added to the resulting array, then they get mangled.

Similar to #14990 (exept that the demo code there runs fine) and the
first source array gets mangled.
Example
=========
<pre><?
$a = array(
'a1' => 1,
'a2' => array( 1, 2, 3 ),
'a3' => array(
'a' => array( 10, 20, 30 ),
'b' => 'b'
)
);
$b = array( 'a1' => 2,
'a2' => array( 3, 4, 5 ),
'a3' => array(
'c' => 'cc',
'a' => array( 10, 40 )
)
);
$c['result'] = array_merge_recursive( $a, $b );
$c['a'] = $a;
$c['b'] = $b;
print_r( $c );
?>
Example Output
================
Array
(
[result] => Array
(
[a1] => Array
(
[0] => 1
[1] => 2
)
[a2] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 3
[4] => 4
[5] => 5
)
[a3] => Array
(
[a] => Array
(
[0] => 10
[1] => 20
[2] => 30
[3] => 10
[4] => 40
)
[b] => b
[c] => cc
)
)
[a] => Array
(
[a1] => 1
[a2] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 3
[4] => 4
[5] => 5
)
[a3] => Array
(
[a] => Array
(
[0] => 10
[1] => 20
[2] => 30
[3] => 10
[4] => 40
)
[b] => b
[c] => cc
)
)
[b] => Array
(
[a1] => 2
[a2] => Array
(
[0] => 3
[1] => 4
[2] => 5
)
[a3] => Array
(
[c] => cc
[a] => Array
(
[0] => 10
[1] => 40
)
)
)
)
