[PHP-DOC] array_unique tribulation continues From: Gyozo Papp (gerzson <email protected>)

You are right.
The examples works as expected with PHP 4.1.1 - Apache 1.3.9
(DSO) on Debian. array_unique() does preserve the *first* key
of every related value.

However, it doesn't seem to work under Win9x, see the following
example:
Array // original
(
    [2] => 4
    [4] => 4
    [8] => 3
    [9] => 4
    [5] => 3
    [7] => 3
)

 Array // array_unique()'d
(
    [9] => 4
    [5] => 3
)

I suggest to you reverting the array_unique section what you
find in rev 1.148 and put a warning about this incompatibilty.
I'll update my bug report (#14805), too.
