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,
