Description:
------------
If you run array_uintersect_assoc and give it an invalid callback for the third argument, you get two error messages. The second one is unnecessary, but it is also wrong as it tells you that you need to pass 3 parameters and that you've actually passed 3.

I've written a patch for array.c to fix it which I've put on pastebin:

Reproduce code:
---------------
<?php
var_dump(array_uintersect_assoc(array(1), array(1), array(1)));
?>

Expected result:
----------------
Warning: array_uintersect_assoc() expects parameter 3 to be a valid callback, array must have exactly two members in Command line code on line 1

NULL


Actual result:
--------------
Warning: array_uintersect_assoc() expects parameter 3 to be a valid callback, array must have exactly two members in Command line code on line 1

Warning: array_uintersect_assoc(): at least 3 parameters are required, 3 given in Command line code on line 1
