[PHP-DEV] array_unique: problems with type array? From: Holger Schopohl (poiujkl <email protected>)

Hi all,

is it correct that the following code
(PHP 4.0.6)

---snip---
$a[1]=array(1,2);
$a[2]=array(2,4);
$b=array_unique($a);
print_r($b);
---snap---

output this?: 

---
Array
(
    [1] => Array
        (
            [0] => 1
            [1] => 2
        )

)
---

instead of:
---
Array
(
    [1] => Array
        (
            [0] => 1
            [1] => 2
        )

    [2] => Array
        (
            [0] => 2
            [1] => 4
        )

)
---

Both entries are not unique and in the documention nobody
write that this case is not allowed.

Regards,
