[PHP-DOC] #21920 [Ver]: array_unique buggy example and BC From: philip <email protected>
Date: 02/05/03

 ID: 21920
 Updated by: philip <email protected>
-Summary: buggy example
 Reported By: corinl <email protected>
 Status: Verified
 Bug Type: Documentation problem
 PHP Version: 4.3.0
 New Comment:

Both examples were wrong but have been updated to reflect current
(4.3.0) behavior. Am leaving this open until someone can figure out
when (or if) the behavior changed. Apparently the second example was
from 4.0.6 but hmm, this is odd. Nothing in NEWS reflects a change.

Maybe the documented example was created on a PHP 4.0.4 box ;)

The docs :
[snip]
Note that keys are preserved. array_unique() sorts the values treated
as string at first, then will keep the first key encountered for every
value, and ignore all following keys. It does not mean that the key of
the first related value from the unsorted array will be kept.
[/snip]
I get the users result on Windows(4.3.0-dev), RH 6.2(4.3.0-dev), Debian
3.0 (5.0.0-dev).

The docs should be changed.

okay, so as you can the *keys* are different!

 Yes, the output on my machine is this. I use the CLI binary.

c:\apache\php>php-cli a_u.php
Array
(
    [a] => gr?n
    [1] => blau
    [2] => rot
)

c:\apache\php>
