Description:
------------
The function [ array_udiff_uassoc() ] is incorrectly implemented. That is, it's the wrong function. The code is identical to the code for [ array_udiff_assoc() ] (note the missing "u"), which is a different function.

The PHP documentation will reveal the major difference--namely, that the [ uassoc ] version takes *two* callbacks: one for keys, one for values. PHP_Compat's version, however, takes only one--which is incorrect.

The given code (it's only one line) will cause the function to generate an "Argument #3 is not an array" error. (If the function [ compareArrayKeys() ] doesn't exist

Test script:
---------------
function compareArrayKeys($a, $b) {
return 0;
}

function compareArrayValues($a, $b) {
return 0;
}

array_udiff_uassoc(array(), array(), 'compareArrayValues', 'compareArrayKeys');

Expected result:
----------------
I expected to not get any warnings, and I expected the function to implement PHP5's [ array_udiff_uassoc() ].

Actual result:
--------------
Warning: array_udiff_uassoc() Argument #3 is not an array in /<...>/include/php/pear/PHP/Compat/Function/array_udiff_uassoc.php on line 56
