Actually this is bogus. From manual:
"array_diff() returns an array containing all the values of
array1 that are not present in any of the other arguments."
In your example, 30 is present in the $array2.

Simpler script:
<?php
$array1 = array (2,2);
$array2 = array (1,2);
print_r($array1);
print_r($array2);
print_r(array_diff($array1,$array2));
?>
Output:
Array
(
[0] => 2
[1] => 2
)
Array
(
[0] => 1
[1] => 2
)
Array
(
)

Description:
------------
See Code.
Thanks for your time.
Reproduce code:
---------------
echo "<pre>";
echo "RUNNING PHP VER 4.2.2 ON RH 9\n";
$array1 = array
(1=>9,2=>10,3=>5,4=>54,5=>30,6=>1,7=>22,8=>22,9=>111,10=>110,11=>30);
$array2 = array
(1=>9,2=>10,3=>5,4=>54,5=>30,6=>1,7=>22,8=>22,9=>111,10=>110,11=>112);
print_r($array1);
print_r($array2);
print_r(array_diff($array1,$array2));
echo "If the last value in array1 (30) is changed to anything other
then 30(that i am aware of) array_diff works right.\nHave I been
smoking too much crack again?\n";
echo "</pre>";
?>
Expected result:
----------------
RUNNING PHP VER 4.2.2 ON RH 9
Array
(
[1] => 9
[2] => 10
[3] => 5
[4] => 54
[5] => 30
[6] => 1
[7] => 22
[8] => 22
[9] => 111
[10] => 110
[11] => 30
)
Array
(
[1] => 9
[2] => 10
[3] => 5
[4] => 54
[5] => 30
[6] => 1
[7] => 22
[8] => 22
[9] => 111
[10] => 110
[11] => 112
)
Array
(
[11] => 30
)
If the last value in array1 (30) is changed to anything other then
30(that i am aware of) it works right.
Have I been smoking too much crack again?
Actual result:
--------------
RUNNING PHP VER 4.2.2 ON RH 9
Array
(
[1] => 9
[2] => 10
[3] => 5
[4] => 54
[5] => 30
[6] => 1
[7] => 22
[8] => 22
[9] => 111
[10] => 110
[11] => 30

[6] => 1
[7] => 22
[8] => 22
[9] => 111
[10] => 110
[11] => 112

If the last value in array1 (30) is changed to anything other then
30(that i am aware of) it works right.
