Here is the smallest programm I could make to reproduce the problem.

<?
    $a[0][0]="Ape1";
    $a[1][0]="Ape2";
    $a[0][one]=&$a[0][0];
    $a[1][two]=&$a[1][0];

    $wrong_a=unserialize( serialize ( $a) );
    echo "Wrong:\n";
    print_r( $wrong_a );
    echo "Right:\n";
    print_r( $a );
?>

Not a bug. 
Making it a feature request.
Duplicate of 10863.

I'm afraid I just don't see the "bug" here. On
my machine, this shows:

Wrong:
Array
(
    [0] => Array
        (
            [0] => Ape1
            [one] => Ape1
        )

    [1] => Array
        (
            [0] => Ape2
            [two] => Ape2
        )

)
Right:
Array
(
    [0] => Array
        (
            [0] => Ape1
            [one] => Ape1
        )

    [1] => Array
        (
            [0] => Ape2
            [two] => Ape2
        )

)

What's the problem?

Well... I thought serialize couldn't handle references at all... but it can (the manual confirms that). So it's not a feature request.

But there IS a bug seomwhere... look at the following output made with PHP-4.0.6 (tested on Windows 2000 and Debian Linux):

Wrong:
Array
(
    [0] => Array
        (
            [0] => Ape1
            [one] => Ape1
        )

    [1] => Array
        (
            [0] => Ape2
            [two] => Array
 *RECURSION*
        )

)
Right:
Array
(
    [0] => Array
        (
            [0] => Ape1
            [one] => Ape1
        )

    [1] => Array
        (
            [0] => Ape2
            [two] => Ape2
        )

)

print_r($wrong_a[1][two]); results in:
Array
(
    [0] => Ape2
    [two] => Array
        (
            [0] => Ape2
            [two] => Array
                (
                    [0] => Ape2
                    [two] => Array
 *RECURSION*
                )

        )

)

This is fixed in CVS. It will be part of 4.0.7. Thanks
for both the report and tracking down the change. :)
