Sorry, reproduce code was incorrect. Correct code is below:
<?php
var_dump(array_unique(array(0,"","0")));
var_dump(array_unique(array("","0",0)));

Description:
------------
In PHP5.2.9RC1, array_unique() returns different result because of
element ordering in array. Reproduce code shows this difference.
It is because SORT_REGULAR never cast array elements and compares them
with ==. I think it's better for SORT_REGULAR to compare elements by
using === instead of ==.
PHP 5.2.9RC1's array_unique() also has backward compatibility ploblem.
Considering backward compatibility, default sort_flag should be
SORT_STRING.
Reproduce code:
---------------
<?php
var_dump(arary_unique(array(0,"","0"))));
var_dump(arary_unique(array("","0",0))));
Expected result:
----------------
I don't know, but 2 results should be same.
Actual result:
--------------
array(1) {
[0]=>
int(0)
}
array(2) {
[0]=>
string(0) ""
[1]=>
string(1) "0"
}
