I could reproduce the same result with PHP 5.2.1 on SuSE Linux
Enterprise Server 9.

Description:
------------
array_slice supports omitting of the $length parameter only if you pass
just the first two parameters (params 1 and 2), but passing the default
value NULL when you want to set $preserve_keys to TRUE (params 1, 2, 3
and 4) does not work.
This would be especially useful for associative arrays.
Reproduce code:
---------------
$a = array(1,2,3);
$b = array('a'=>1,'b'=>1,'c'=>2);
var_dump(array_slice($a, 1), array_slice($a, 1, 2, TRUE),
array_slice($a, 1, NULL, TRUE), array_slice($b, 1), array_slice($b, 1,
2, TRUE), array_slice($b, 1, NULL, TRUE));
Expected result:
----------------
array(2) {
[0]=>
int(2)
[1]=>
int(3)
}
array(2) {
[1]=>
int(2)
[2]=>
int(3)
}
array(2) {
[1]=>
int(2)
[2]=>
int(3)
}
array(2) {
["b"]=>
int(1)
["c"]=>
int(2)
}
array(2) {
["b"]=>
int(1)
["c"]=>
int(2)
}
array(2) {
["b"]=>
int(1)
["c"]=>
int(2)
}
Actual result:
--------------
array(2) {
[0]=>
int(2)
[1]=>
int(3)
}
array(2) {
[1]=>
int(2)
[2]=>
int(3)
}
array(0) {
}
array(2) {
["b"]=>
int(1)
["c"]=>
int(2)
}
array(2) {
["b"]=>
int(1)
["c"]=>
int(2)
}
array(0) {
}
