array_unique() always returns only 1 result for multi-dimentional arrays
Here is the code:
$temp = Array (
Array('a', 'b'),
Array('x', 'y'),
);
print_r($temp);
print_r(array_unique($temp));
Here is the result in PHP 4.0.4, as it should be, i.e. no array change:
Array
(
[0] => Array
(
[0] => a
[1] => b
)
[1] => Array
(
[0] => x
[1] => y
)
)
Array
(
[0] => Array
(
[0] => a
[1] => b
)
[1] => Array
(
[0] => x
[1] => y
)
)
Here is the result in PHP 4.0.6:
Array
(
[0] => Array
(
[0] => a
[1] => b
)
[1] => Array
(
[0] => x
[1] => y
)
)
Array
(
[0] => Array
(
[0] => a
[1] => b
)
)
I have put the code at http://www.99servers.com/develop/test/array_unique.php,
you can see the results by yourself.
My phpinfo() is located at http://www.99servers.com/develop/test/phpinfo.php,
just in case you need additional details about my php 4.0.6 configuration.
