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

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
